550da471be stm32: Remove OptionalPin 
The idea behind OptionalPin has a few problems:

- you need to impl the signal traits for NoPin which is a bit weird https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L413-L416
- you can pass any combination of set/unset pins, which needs checking at runtime  https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L130

The replacement is to do multiple `new` constructors for each combination of pins you want to take.

cdc66e110f stm32/rcc: remove builders on Config. 
This makes API consistent with other Config structs in Embassy, where
the convention is to not use builders.

3811c0a401 Add adapter for implementing async traits for blocking types 
This allows writing drivers relying on async traits, while still
functioning with implementations that already implement the embedded-hal
traits.

Add examples to stm32l4 for using this feature.
