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`.

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.

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.
