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: https://github.com/fivdi/pico-i2c-dma/blob/7ebfd553f3ce5b5b210d53102b0ecca158172633/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.

Rename from {Rx,Tx}BufferedUart to BufferedUart{Rx,Tx} to be compliant with stm32 and nrf implementations

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.

Add BufferedUart implementation, and feature-guard time-driver initialization, to free up TIMER peripheral if not used with embassy executor

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.

965: (embassy-rp): add RP2040 ROM functions and intrinsics aliases r=Dirbaio a=MathiasKoch

Add RP2040 ROM functions described in section **2.8.3.1. Bootrom Functions** of https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.pdf



Make all ROM functions (normal and floating point) provide both a direct
call that does the operation and a module with a ptr() function to get
the function pointer.

Add a feature to enable automatic caching of the result of ROM table
function lookups.

Add a check for a V2 bootrom when using floating point functions that
require it.  Panic when it's not present.

Add a standardized macro for intrinsics export and connect the simple
ROM functions to intrinsics.

Direct copy from `rp-hal`! Full credit to those guys for all the heavy lifting.
