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`.

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 `_`.

6179da6b9c stm32/dma: eagerly start transfers when calling the functions. 
`async fn`s do nothing until polled, but we want the DMA transfer to
immediately start in this case. Drivers rely on it. Some require special
orders, such as "start DMA, start SPI, then wait for DMA" which is awkward
to do without eager start.

Also use a manually-impl'd future, this allows getting rid of the "double"
Unborrow channel clone.
