540: Initial support for STM32F3 r=Dirbaio a=VasanthakumarV
The [companion PR](https://github.com/embassy-rs/stm32-data/pull/109) in `stm32-data` should be merged before this PR.
The examples were tested on an STM32F303VC MCU.

543: Incrementally merge STM32 SPI versions, Part 3 r=Dirbaio a=GrantM11235
Notable changes:
- `SPE` is now disabled before `TXDMAEN` and `RXDMAEN` are disabled. This is the "mandatory" sequence for v2 and v3 (and maybe v1 as well, but I can't find it in the reference manual).
- v1's `write_dma_u8` now waits for idle and disables `TXDMAEN` after the transfer is complete, just like everything else.

A new `split` method is introduced such that the Uarte tx and rx can be used from separate tasks. An MPSC is used to illustrate how data may be passed between these tasks.
542: nrf/gpiote: remove PortInput, move impls to Input/FlexPin. r=Dirbaio a=Dirbaio
`PortInput` is just a dumb wrapper around `Input`, it has no reason whatsoever to exist. This PR moves the `wait_for_x` functionality to `Input` directly.
It also adds it to `FlexPin` for completeness and consistency with `Input`.
(The reason `PortInput` exists is a while ago `GPIOTE` was an owned singleton that you had to initialize, so `PortInput::new()` would require it to enforce it's been initialized. This doesn't apply anymore now that GPIOTE is "global")

533: Book poc r=Dirbaio a=lulf
This is a Proof of Concept for an embassy book. It's using Antora/Asciidoc.
* Asciidoc because it's a single specification with a slightly richer feature set than markdown.
* Antora because it allows keeping content in the embassy repo, while book definition in another repo (embassy-book).
Using antora also allows for easy embedding of embassy doc in other projects, which I think in turn increases probability of upstream contributions.
The sources of content are located in docs/ but could also be in a separate repo. However, keeping it in the embassy repo makes it easier to support one version of the book per embassy version in the future.
At present, the book is automatically built every hour from this branch and published at: https://embassy-rs.github.io/embassy-book/embassy/dev/index.html
