Merge #992

992: (embassy-stm32): remove flash lock/unlock public API from stm32 flash r=lulf a=MathiasKoch

Instead, perform the unlocking and locking automatically on erase and write operations.

This makes the `embedded-storage` abstraction actually useable in libraries, while still keeping the flash peripheral locked the majority of the time.
