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.

Old code used `cfg_if!` because rustc still parses code inside disabled cfg's, and Rust stable at that time couldn't parse the new GAT where-clause location. This is not the case anymore.

stm32 usart: Fix RX interrupt flag handling
...
* On v1 interrupts cannot be cleared individually.
Instead they are cleared implicitly by reading or writing DR (which we do now).
* Multiple error flags can be set at the same time:
Handle them all in one go intstead of re-entering the ISR for each one so that
we do not lose any error flags on v1 hardware.
* Wake when the RX buffer becomes full: This allows fast running chips to pull data
from the buffer before receiving the next byte.
