SSL support in asyncio, sorted qstr pools, common machine module bindings

This release of MicroPython introduces SSL/TLS support to asyncio, for both
the client and server sides.  The interface matches CPython:
`asyncio.open_connection()` and `asyncio.start_serve()` now both accept an
`ssl` argument to supply an `SSLContext` object.  As part of this, new
methods were added to `SSLContext` to load certificates, and certificate
date/time validation was enabled on all ports that use mbedTLS.

Qstr pools are now sorted, which provides a significant performance boost
for `qstr_find_strn()`, which is called a lot during parsing and loading of
.mpy files, as well as interning of string objects, which happens in most
string methods that return new strings.  The static pool (part of the .mpy
ABI) isn't currently sorted, but could be in the future.

There have been many internal changes to the `machine` module (and on some
ports the `os` module) to factor the Python bindings to a common location,
reduce code duplication and make the API more consistent across all the
ports.  And a new `boardgen.py` script has been added to factor pin
generation and enable a more consistent `machine.Pin` across ports.  For
consistency, the following user-facing changes have been made:

- cc3200 port: The `machine` module gains `soft_reset()`, `mem8`, `mem16`,
  `mem32` and `Signal`; it loses `POWER_ON` (replaced by `PWRON_RESET`).
  `disable_irq()` now returns an (opaque) integer rather than a bool, and
  `enable_irq(state)` must be passed an argument which is the return value
  of `disable_irq()`, rather than a bool.  In the `os` module, `dupterm()`
  has been converted to use the common implementation and has semantics the
  same as other ports, and `uname()` is removed to save space (sys.version
  and sys.implementation can be used instead).

- esp32 port: In the `machine` module, `lightsleep()` and `deepsleep()` no
  longer take the `sleep` keyword argument, instead it's positional to
  match other ports.  Also, passing 0 here will now do a 0ms sleep instead
  of acting like nothing was passed.  And `reset_cause()` no longer accepts
  any arguments (before it would just ignore them).

- esp8266 port: `machine.idle()` now returns None instead of the time
  elapsed.  The `machine.WDT()` constructor now takes keyword arguments,
  and accepts the `timeout` argument but raises an exception if it's not
  the default value (this port doesn't support changing the timeout).

- mimxrt port: `machine.freq()` now accepts an argument but raises
  `NotImplementedError`, and `machine.lightsleep()` has been added but also
  just raises `NotImplementedError` (this is to make these functions use an
  implementation common to the other ports).

- nrf port: The `machine` module gains `unique_id()` (returns an empty
  bytes object), `freq()` (raises `NotImplementedError`) and `Signal`.
  `UART.sendbreak()` is removed, but this method previously did nothing.
  The `os.dupterm()` function has changed to match the semantics used by
  all other ports (except it's restricted to accept only `machine.UART`
  objects).

- qemu-arm port: The `machine` module gains `soft_reset()` and `idle()`.

- samd port: The `machine.deepsleep()` function now resets after sleeping.

- unix port: Gains `machine.soft_reset()`.

- zephyr port: The `machine` module gains `soft_reset()`, `mem8`, `mem16`,
  and `mem32`.  The `UART` class gains the following methods: `init()`
  which supports setting `timeout` and `timeout_char`, `deinit()` which
  does nothing, `flush()` which raises `OSError(EINVAL)` because it's not
  implemented, and `any()` and `txdone()` which both raise
  `NotImplementedError`.

The teensy port has been removed in this release.  This port was largely
unmaintained, had limited features (the only hardware support was for GPIO
and timer, and no `machine` module), and only supported a small number of
Teensy boards.

A new preview versioning scheme has been introduced, whereby non-release
builds are a preview of the next, upcoming release.  This scheme is
compatible with semver and should help to eliminate confusion matching
documentation and firmware version numbers, among other things.

Black has been replaced with ruff format as the Python code formatter.
This required a few small changes to Python code, and now allows linting
and formatting with ruff.

Bound method instances now support comparison and hashing, matching CPython
semantics.  The .mpy sub-version has been updated from 6.1 to 6.2 due to a
change in the native .mpy ABI.  A new option `MICROPY_PREVIEW_VERSION_2`
has been added which provides a way to enable features and changes slated
for MicroPython 2.x, by running `make MICROPY_PREVIEW_VERSION_2=1`.  This
is an alternative to having a 2.x development branch, and any feature or
change that needs to be "hidden" until 2.x will use this flag.

LittleFS has been updated to v2.8.1.  The associated MicroPython VfsLfs2
driver can read existing LFS2 filesystems, but any writes will update the
filesystem to a newer LFS2 version that cannot be read by older drivers, so
take this into account when updating, for example update mboot first.

The VFS sub-system has a new file ioctl to set the read-buffer size, which
is used by mpremote to significantly increase performance of the
"mpremote mount" feature.  Manifest files now allow registering an external
library path via `add_library(name, path)`.  `sys.stdout.buffer.write()`
now returns the actual number of bytes written (although this is
complicated when output goes to multiple destinations).

The esp32 port has been updated to use IDF version 5.0.4, and the initial
GC heap size tuned so that, after doubling the heap size, WiFi can still be
started and an SSL connection made.  `RMT.source_freq()` is now a class
method, socket connect timeout has been implemented, RTC user memory is now
preserved over most reset causes, and `hashlib.md5` enabled.

The mimxrt port has RTC alarm/wakeup functionality added, along with
support for `machine.deepsleep()`.

The rp2 port sees the introduction of a new `rp2.DMA` class for control
over DMA transfers.  It has switched to use the same math library as other
ports to get more accurate floating point behaviour, and enabled
`os.dupterm_notify()` for WebREPL use.  The TinyUSB stack is now scheduled
to run from the IRQ handler (instead of polled in the VM) which slightly
improves performance of the VM and USB.  The port also makes better use of
event scheduling and WFE to be more efficient.  It also has added support
for external ADC channels (for example when using the ninaw10 driver).

The stm32 port has improved support for STM32H5xx MCUs, including Ethernet
support, frequency scaling with HSI, sleep mode and SD card support.  The
NUCLEO_WL55 board now freezes in the LoRa driver, the I2S driver has
improved accuracy of the clock frequency, and mboot now supports Microsoft
WCID to set the USB driver.

New boards added in this release are: UM_TINYWATCHS3 (esp32 port),
POLOLU_3PI_2040_ROBOT, POLOLU_ZUMO_2040_ROBOT and SIL_RP2040_SHIM (rp2
port), NUCLEO_H563ZI (stm32 port).

The change in code size since the previous release for various ports is
(absolute and percentage change in the text section):

       bare-arm:   +216  +0.381%
    minimal x86:   +624  +0.340%
       unix x64:  +8283  +1.050%
          stm32:  +1368  +0.350%
         cc3200:  +1184  +0.649%
        esp8266:   +800  +0.114%
          esp32: +35348  +2.100%
         mimxrt:  +2172  +0.602%
     renesas-ra:    +96  +0.015%
            nrf:  +1460  +0.785%
            rp2:  +6100  +1.880%
           samd:  +1476  +0.568%

The changes that dominate these numbers are:
- bare-arm, minimal: comparing and hashing bound methods, sorted qstr pools
- unix: updating LittleFS to 2.8.1, enabling certificate date/time
  validation, adding SSLContext certificate methods, asyncio SSL support
- stm32: sorted qstrs, updating LittleFS to 2.8.1, I2S clock frequency
  improvements, asyncio SSL support
- cc3200: sorted qstrs, more machine module functions, use of the common
  `os.dupterm` implementation
- esp32: switching ESP-IDF from 5.0.2 to 5.0.4
- esp8266: updating LittleFS to 2.8.1
- mimxrt: adding RTC alarm/wakeup functionality, updating LittleFS to
  2.8.1, asyncio SSL support
- nrf: updating LittleFS to 2.8.1, enabling `machine.Signal`, asyncio SSL
  support
- rp2: using locally-provided math library, adding new `rp2.DMA` class
- samd: sorted qstrs, updating LittleFS to 2.8.1, asyncio SSL support

With the new sorted qstr pools, performance is significantly improved for
qstr-heavy operations, between +50% and +200% improvement.  Other areas
have their performance unchanged since the last release.
