refactor(iroh)!: Move blobs and tags rpc client and server to iroh-blobs (#2874)

## Description

Move blobs and tags rpc client and server to iroh-blobs.

Depends on n0-computer/iroh-blobs#7

Todo:

- [x] merge n0-computer/iroh-blobs#7

## Breaking Changes

- Lots of types in client::blobs and client::tags become reexports
- blob share goes away, since it requires the node client

## Notes & open questions

I want to keep the client::blobs and client::tags modules
self-contained, so the idea is that these will reexport all the things
from iroh-blobs::rpc::client that a user will need (except I have
probably forgotten something). Maybe I should use wildcard exports here
even though people dislike them... ?

~~The client::blobs::Client itself is *not* a reexport but a newtype to
hide the ugly type parameters. Same for client::tags::Client.~~

With the changes in quic-rpc, these are now just module reexports!

The Blobs protocol handler now takes an Endpoint, since that was needed
to implement one of the functions.
