938: Do not use cfg_if for embedded-hal-async feature gates. r=Dirbaio a=Dirbaio
Old code used `cfg_if!` because rustc still parses code inside disabled cfg's, and Rust stable at that time couldn't parse the new GAT where-clause location. This is not the case anymore.

Ensures that nRF saadc sampling is stopped and is awaited prior to exiting the two sampling methods. Not doing so causes a potential power drain and the potential for dropped buffer writes when having finished continuous sampling.
871: nrf/saadc: add type-erased AnyInput. r=Dirbaio a=Dirbaio
872: nrf/usb: prevent user code from constructing a PowerUsb directly. r=Dirbaio a=Dirbaio
PowerUsb must be constructed through `new()` so that it sets up the IRQ.
It must have at least one private field, otherwise user code can construct
it directly with `PowerUsb{}`.

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.~~

Eliminated a signal by using a simpler trait method that returns whether VBus power is available. Also includes a UsbSupply that can be signalled for use with the nRF softdevice. Includes the requirement for waiting for power to become available.
Allow creating UarteRx/UarteTx directly. This allows using uart unidirectionally
(rx-only or tx-only), without having to 'waste' a pin for the unused direction.
- Move Interrupt and InterruptExecutor from `embassy` to `embassy-cortex-m`.
- Move Unborrow from `embassy` to `embassy-hal-common` (nothing in `embassy` requires it anymore)
- Move PeripheralMutex from `embassy-hal-common` to `embassy-cortex-m`.
Following the project's decision that "leak unsafe" APIs are not marked as "unsafe",
update PeripheralMutex to accept non-'static state without unsafe.
Fixes#801
