Add a STM32/DMARingBuffer::read_exact helper

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.

428a4ba3f9 stm32/gpdma: clear all interrupts after reset.
Reset doesn't clear them, this causes subsequent transfers to instantly
complete because the TC flag was set from before.

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`.

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.
