Merge #1287

1287: stm32: use stm32-metapac from crates.io, remove stm32-data submodule. r=Dirbaio a=Dirbaio

- `embassy-stm32` uses `stm32-metapac` from `crates.io`.
- Remove `stm32-data` submodule.
- Remove `stm32-metapac`, `stm32-metapac-gen`. These are now in the `stm32-data` repo.
- Remove `stm32-gen-features`, since it used `stm32-data` directly.
  - The feature list in `stm32-metapac` is generated by `stm32-metapac-gen` now.
  - The feature list in `embassy-stm32` can be updated by hand by copypasting from `stm32-metapac`'s `Cargo.toml`. We can add a script to do this automatically later if that's too annoying.
- Remove outdated `xtask` scripts that no longer work. Not needed anymore, you can run CI locally by doing `./ci.sh`.
