- 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`.
1227: stm32/dma: fix spurious transfer complete interrupts r=Dirbaio a=pattop
DMA interrupts must be acknowledged by writing to the DMA_{L,H}IFCR
register.
Writing to the CR register is unnecessary as the channel (EN bit) is
disabled by hardware on completion of the transfer.

- 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`.
Previously, every dma interrupt handler called the same `on_irq`
function which had to check the state of every dma channel.
Now, each dma interrupt handler only calls an `on_irq` method for its
corresponding channel or channels.
These files end up containing chip-specific info, so they deduplicate
really badly when building docs for all 1200 chips.
The doc generator removes files starting with `_`.
