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.

855: PDM microphone support for nrf r=Dirbaio a=pbert519

PDM microphones have a long startup phase, therefore the driver samples continuously and only switches the target buffer if the user requests sampling.

e1faf88607 Removes some of the code duplication for UarteWithIdle
This commit removes some of the code duplication for UarteWithIdle at the expense of requiring a split. As the example illustrates though, this expense seems worth the benefit in terms of maintenance, and the avoidance of copying over methods. My main motivation for this commit was actually due to the `event_endtx` method not having been copied across.

958: Implement proper `Drop` for `BufferedUarte` r=lulf a=ZoeyR

The drop method in `BufferedUarte` was prone to hanging indefinitely and also didn't actually disable the peripheral. I mostly copied over the drop method from `Uarte` with some modifications since `BufferedUarte` could have a transmit lasting indefinitely.

I haven't completed testing this yet. I'm creating this PR early so that I can get corrected if I went way off course.

This PR adds a `split()` method to `BufferedUarte` as discussed on matrix.

810: Takes care of power for nRF USB devices r=Dirbaio a=huntc

Modifies the usb-serial example to illustrate how to setup USB for situations where the USB power can be detected and removed.

Gaps:

~~* No support for the nrf-softdevices as yet, although this should be possible via another constructor.~~
* No support for the nrf5340, although this should be possible via USBREG.

The change is tested and appears to work. Some notes:

* There's an existing field named self_powered as a UsbDevice field. It doesn't ever appear to get set. I'm wondering if this field is intended to signal that a device has the nRF VBUS power situation or not. I'm not presently using it.
* The new PowerDetected event is generated on the bus initially in situations where just new is used i.e. without power management, including on STM. We can therefore rely on this event always being generated.

Old description:

~~EnabledUsbDevice is a wrapper around the `UsbDevice` where its enablement is also subject to external events, such as `POWER` events for nRF. It is introduced generically to support other platforms should they also require external signaling for enablement.~~

The field is "sort of" deprecated, it was made optional recently:

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