Weak handle migration (#17695)

# Objective

- Make use of the new `weak_handle!` macro added in
#17384

## Solution

- Migrate bevy from `Handle::weak_from_u128` to the new `weak_handle!`
macro that takes a random UUID
- Deprecate `Handle::weak_from_u128`, since there are no remaining use
cases that can't also be addressed by constructing the type manually

## Testing

- `cargo run -p ci -- test`

---

## Migration Guide

Replace `Handle::weak_from_u128` with `weak_handle!` and a random UUID.
