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`.

977a7906e4 stm32 uart: Fix error flag handling for blocking operations 
Clear and report the error flags one by one and pop the data byte only
after all error flags were handled.

For v1/v2 we emulate the v3/v4 behaviour by buffering the status
register because a read to the data register clears all flags at once
which means we might loose all but the first error.

1034: stm32/usart: Fix bug where USART idle flag could end a `read` prematuraly r=Dirbaio a=guillaume-michel

on STM32, when setting USART `detect_previous_overrun = true`, the idle flag is not cleared and could result in premature end of the `read` method.

This PR fixes that.

8ba421f324 Do not use cfg_if for embedded-hal-async feature gates.
