Merge #959 
959: Generic, executor-agnostic queue implementation r=ivmarkov a=ivmarkov

Hopefully relatively well documented.

Implementation relies on a fixed-size `SortedLinkedList` from `heapless`. (By default, for up to 128 timer schedules, but we can lower this number to - say - 64.)

As discussed earlier, on queue overflow, the `WakerRegistration` approach is utilized, whereas the waker that is ordered first in the queue is awoken to make room for the incoming one (which might be the waker that would be awoken after all!). Wakers are compared with `Waker::will_wake`, so the queue should actually not fill up that easily, if at all.

I've left provisions for the user to manually instantiate the queue using a dedicated macro - `generic_queue!` so that users willing to adjust the queue size, or users (like me) who have to use the queue in a complex "on-top-of-RTOS-but-the-timer-driver-calling-back-from-ISR" scenario can customize the mutex that protects the queue.

The one thing I'm not completely happy with is the need to call `{ embassy_time::queue::initialize() }` early on before any futures using embassy-time are polled, which is currently on the shoulders of the user. I'm open to any ideas where we can get rid of this and do it on the first call to `_embassy_time_schedule_wake`, without introducing very complex combinations of critical sections, atomics and whatnot.

984: rp pico async i2c implementation r=Dirbaio a=jsgf

This implements an interrupt-driven async i2c master. It is based on https://github.com/embassy-rs/embassy/pull/914, a bit of https://github.com/embassy-rs/embassy/pull/978 and `@ithinuel's` https://github.com/ithinuel/rp2040-async-i2c.git

This is still work-in-progress, and is currently untested.

1006: Removes some of the code duplication for UarteWithIdle r=Dirbaio a=huntc

This PR removes some of the code duplications for `UarteWithIdle` at the slight expense of requiring a split when using idle processing. As the nRF example illustrates though given the LoC removed, this expense seems worth the benefit in terms of maintenance, and the avoidance of copying over methods. My main motivation for this PR was actually due to the `event_endtx` method not having been copied across to the idle-related code.

Tested the uart_idle example on my nRF52840-dk, and from within my app. Both appear to work fine.

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.

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.

e757b1882e Add inline attribute to embassy-rp async functions 
This commit adds the inline attribute to the recently added async gpio
functions. This is to enable cross-crate inlining and to be consistent
with the other functions implemented for Input and Flex.

1f746e0939 Remove the authors field from Cargo.tomls 
It currently contains whoever was first to write some code for the crate,
even if many more people have contributed to it later.

The field is "sort of" deprecated, it was made optional recently:
https://rust-lang.github.io/rfcs/3052-optional-authors-field.html

Due the the reasons listed there I believe removing it is better than
setting it to generic fluff like "The Embassy contributors".
