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.

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.

960: Add non blocking Bxcan constructor r=Dirbaio a=andyblarblar
This PR adds a non-blocking constructor to the Bxcan Can wrapper struct. This allows for the creation of the Can periferal without blocking for a sync with the Can bus.

971: (embassy-boot): add blocking API to FirmwareUpdater r=lulf a=MathiasKoch
Also add a split `prepare_update` + `write_firmware` API, to allow for an optimized update API at the exchange of added complexity.
The old API is left in place to allow users to choose the complexity level that fits their needs.

961: Parameterize Signal with RawMutex r=ivmarkov a=ivmarkov
The `RawMutex` parameter is deliberately chosen to be the second one, so as it can take as a default `CriticalSectionRawMutex`. This way backwards compatibility is preserved, and users utilizing the `critical-section` crate everywhere can just continue to use the more ergonomic single-generic-parameter version of Signal.
I'm thinking we should probably do the same for `Channel`, and move the `RawMutex` parameter as the last one in the list, with a `CriticalSectionRawMutex` being its default. But that's a backwards-incompatible change of course.
