914: (embassy-rp): Add I2C master implementation r=Dirbaio a=MathiasKoch
This PR adds both blocking and DMA based async implementations of I2C master.
Both E-H 0.2 & E-H 1.0 abstractions are implemented as well.
### Questions & concerns:
- Do we need an I2C interrupt handler (for transfer done, abort & error handling?) (async only)
- Do we need to add some automatic attempt at unblocking an I2C bus in case of failures (see ref: 7ebfd553f3/src/i2c_dma.c (L116-L142))
- Should I add `vectored_{read, write}` implementations?

934: (embassy-rp): Add Buffered UART implementation r=MathiasKoch a=MathiasKoch
### Questions & concerns:
- ~~Would it make sense to add `RxBufferedUart` and `TxBufferedUart`, for cases where you would want to only buffer one way?~~
- ~~Do I need to be monitoring more interrupt flags than `Receive` & `Receive timeout`?~~
This PR adds working `BufferedUart` implementation, along with `RxBufferedUart` and `TxBufferedUart`. The implementation leaves room for improvement with respect to performance, as it still does not utilize DMA nor the internal UART buffers.

973: Rework STM32 BufferedUart internals so we can split into Rx and Tx like embassy-nrf r=lulf a=guillaume-michel
Context:
On STM32, BufferedUart is not splittable into Rx and Tx part like the non buffered version. On embassy-nrf, a RefCell is used to make BufferedUarte splittable.
Description:
This PR add the possibility to split BufferedUart into Rx and Tx without adding breaking changes.
Hope somebody find it useful

977: Use firmware writer in stm32{f7, h7} example app r=lulf a=lulf
The new FirmwareWriter is useful in particular for these architectures due to the large erase sector size.

This commit adds the allow(unused) attribute to functions and constants
that are not currently used. There is one warning remaining but
https://github.com/embassy-rs/cyw43/pull/23 attempts to address that
one. The constants have been moved into a module to allow the attribute
to be applied to the module as a whole.
The motivation for this is that it will hopefully make it easier to
spot new warnings that might be introduced by new, or updated code.
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.
