4883fdd154 Add a STM32/DMARingBuffer::read_exact helper
This provides a helper function with an async implementation, that
will only return (or error) when it was able to read that many bytes,
sleeping until ready.

Additionally, corrected the documentation for Ringbuffer functions to use
"elements" instead of "bytes" as the types were already generic over the
word/element size.

bbc81146ec BDMA: request stop after busy loop in blocking_wait().
Otherwise the channel cannot be used again, since CR.EN remains set
and the DMA channel registers are read-only while it is set.

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`.

- 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`.

8c45c98e41 stm32: Refactor DMA interrupts
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.

53d9a0b516 stm32: exclude spammy files from docs by prefixing with _.
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 `_`.
