613: Rust stable support r=Dirbaio a=Dirbaio

This PR adds (limited) stable Rust support!

The drawbacks are: 

- No `#[embassy::task]`, `#[embassy::main]`. (requires `type_alias_impl_trait`). You have to manually allocate the tasks somewhere they'll live forever. See [example](https://github.com/embassy-rs/embassy/blob/master/examples/nrf/src/bin/raw_spawn.rs)
- No async trait impls (requires GATs). Note that the full API surface of HALs is still available through inherent methods: #552 #581 
- Some stuff is not constructible in const (requires `const_fn_trait_bound`), although there's an (ugly) workaround for the generic `Mutex`.

So it's not that bad in the end, it's fully usable for shipping production-ready firmwares. We'll still recommend nightly as the default, until GATs and `type_alias_impl_trait` are stable.

607: stm32: Add standard crate-wide macros for pin/dma traits r=Dirbaio a=Dirbaio

All drivers will declare the traits using these macros.

This has a few implications:
- ALL drivers will have an Instance trait, even for drivers that usually have only one instance (for example crc, eth)
- It's no longer possible to have a fn configure() in pin traits, drivers will have to do that some other way

In the future, build.rs will generate all the impls instead of macrotables.

Pin/Dma traits are no longer explicitly sealed, since gpio::Pin and dma::Channel are already sealed, which has the same effect. This means the `af_num()` and `request()` funcs are now public, but IMO that's okay, they're unlikely to change.

605: stm32: Remove OptionalPin r=Dirbaio a=Dirbaio

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.

604: Add embassy-boot r=lulf a=lulf

Continuation of https://github.com/embassy-rs/embassy/pull/588

Embassy-boot is a simple bootloader that works together with an application to provide firmware update capabilities with a minimal risk.

The bootloader consists of a platform-independent part, which implements the swap algorithm, and a platform-dependent part (currently only for nRF) that provides addition functionality such as watchdog timers softdevice support.

The bootloader is intended to be configurable for different flash sizes and architectures, and only requires that embedded-storage flash traits are implemented.

The nRF version can be configured programatically as a library, or using linker scripts to set the partition locations for DFU, ACTIVE and STATE

* DFU: Where the next firmware version should be written. This is used by the FirmwareUpdater
* ACTIVE: Where the current firmware version resides. Written by bootloader when swap magic is set
* STATE: Contains the bootloader magic and the copy progress. Can be 1-N pages long (depending on how much flash you have which will determine the copy progress index size
