rp async i2c: raise the tx_empty threshold
...
Assert "tx_empty" interrupt a little early so there's time to wake up
and start refilling the fifo before it drains. This avoids stalling the
i2c bus if the tx fifo completely drains.

rp i2c: clean up tx_abrt handling
...
Make sure we always wait for the stop bit if there's a reason to -
either because we sent one, or because there was a hardware tx abort.

embassy-rp: async i2c implementation
...
This is an interrupt-driven async i2c master implementation. It makes as
best use of the RP2040's i2c block's fifos as possible to minimize
interrupts.
It implements embedded_hal_async::i2c for easy interop.
WIP async impl

972: Restructure USB crates r=Dirbaio a=Dirbaio
- Split driver from `embassy-usb` to a separate crate. This allows making breaking changes to `embassy-usb` without having to bump all the crates with driver impls, such as HALs.
- Merge classes into `embassy-usb`. Now that breaking changes to `embassy-usb` aren't that bad, having everything in a single crate is much easier.
