Merge #601
601: [part 1/n] Change macrotables to build.rs codegen r=lulf a=Dirbaio

This PR replaces the "macrotables" (the macros like `stm32_data::peripherals!`) with a `const METADATA`.

Macrotables had some problems:

- Hard to debug
- Somewhat footgunny (typo the "pattern" and then nothing matches and the macro now expands to nothing, silently!)
- Limited power
  - Can't count, so we had to add a [special macrotable for that](f50f3f0a73/embassy-stm32/src/dma/bdma.rs (L26)).
  - Can't remove duplicates, so we had to fallback to [Rust code in build.rs](f50f3f0a73/embassy-stm32/build.rs (L105-L145))
  - Can't include the results as a listto another macro, so again [build.rs](https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/build.rs#L100-L101).

They work fine for the 95% of cases, but for the remaining 5% we need Rust code in build.rs. So we might as well do everything with Rust code, so everything is consistent.

The new approach generates a `const METADATA: Metadata = Metadata { ... }` with [these structs](https://github.com/embassy-rs/embassy/blob/unmacrotablize/stm32-metapac-gen/src/assets/metadata.rs) in `stm32-metapac`. `build.rs` can then read that and generate whatever code.

8bb41a3281 stm32f3: fix nonexistent cfg tests
The rcc code was taken from stm32-rs which uses 'x' features, but
embassy uses features with full chip names.

Add these 'x' wildcards as cfgs and use them in rcc.
They will be useful for USB too.
