646: Debloat stm32-metapac r=Dirbaio a=Dirbaio
- Remove usage of `peripheral_counts!` macrotables.
- Remove `dbgmcu!` macrotable.
- Move the remaining macrotables to embassy-stm32 build.rs. This brings metapac decompressed size from ~250mb to ~100mb
- Deduplicate files with identical metadata. This brings decompressed size from ~100mb to ~70mb, compressed from ~10mb to ~4mb, which is finally small enough to publish on crates.io!

645: stm32 usart: Fix RX interrupt flag handling r=lulf a=timokroeger
* 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.
Tested on v1 hardware, lets see if v2 still succeeds on CI.

618: time: optimize math by reducing fractions at compile time. r=Dirbaio a=Dirbaio
For example, `as_micros`, `from_micros` now are noops if tick rate is 1MHz.
