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.

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.

602: Add stm32 USB OTG peripherals r=Dirbaio a=chemicstry

Fixes #557. This is similar to #580, but for synopsys IP.

I could add examples to other chips, but I have no way of testing them. The F4 example is tested and working.

558: Port buffered uart to v1 stm32 hardware r=Dirbaio a=DCNick3

#526 seems to suggest that it will be rewritten for DMA support, but I am not sure how to implement it and the port was quite straightforward, so here it is. It might be immediately useful before DMA version will be implemented

Note that I have not tested this on v2 hardware

6179da6b9c stm32/dma: eagerly start transfers when calling the functions.
`async fn`s do nothing until polled, but we want the DMA transfer to
immediately start in this case. Drivers rely on it. Some require special
orders, such as "start DMA, start SPI, then wait for DMA" which is awkward
to do without eager start.

Also use a manually-impl'd future, this allows getting rid of the "double"

482: Add MCO peripheral. r=Dirbaio a=matoushybl

This PR adds an abstraction over STM32 RCC feature called MCO (Microcontroller Clock Output). The clock output can bind to several clock sources and then can be scaled using a prescaler.

Given that from the embassy ecosystem the RCC is generaly invisible to the user, the MCO was implemented as a separate peripheral bound to the pin where the clock should appear.
