b857334f92 STM32: Fix race in alarm setting, which impacted scheduling. 
Detect potential race condition (should be rare) and return false back
to caller, allowing them to handle the possibility that either the
alarm was never set because it was in the past (old meaning of false),
or that in fact the alarm was set and may have fired within the race
window (new meaning of false). In either case, the caller needs to
make sure the callback got called.

Add implementation note for embassy-stm32's time-driver 
This is a detail I didn't originally understand when hoping to use TIM16/17 as alternative embassy-time driver providers.

Adding my note here to hopefully save the next person a little time.

921780e6bf Make interrupt module more standard. 
- Move typelevel interrupts to a special-purpose mod: `embassy_xx::interrupt::typelevel`.
- Reexport the PAC interrupt enum in `embassy_xx::interrupt`.

This has a few advantages:
- The `embassy_xx::interrupt` module is now more "standard".
  - It works with `cortex-m` functions for manipulating interrupts, for example.
  - It works with RTIC.
- the interrupt enum allows holding value that can be "any interrupt at runtime", this can't be done with typelevel irqs.
- When "const-generics on enums" is stable, we can remove the typelevel interrupts without disruptive changes to `embassy_xx::interrupt`.

5085100df2 Add embassy-cortex-m crate. 
- 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`.
