The replacement is `embassy-usb`. There's a WIP driver for stm32 USBD in #709,
there's no WIP driver for stm32 USB_OTG. This means we're left without
USB_OTG support for now.
Reason for removing is I'm going to soon remove `embassy::io`, and
USB uses it. I don't want to spend time maintaining "dead" code
that is going to be removed. Volunteers welcome, either to update
old USB to the new IO, or write a USB_OTG driver fo the new USB.
* Add flash drivers for L0, L1, L4, WB and WL. Not tested for WB, but
should be similar to WL.
* Add embassy-boot-stm32 for bootloading on STM32.
* Add flash examples and bootloader examples
* Update stm32-data
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.

This allows writing drivers relying on async traits, while still
functioning with implementations that already implement the embedded-hal
traits.
Add examples to stm32l4 for using this feature.
* Adds an executor for WASM runtimes based on wasm_bindgen.
* Add time driver based on JS time handling.
* Add example that can run in browser locally.
* Update to critical-section version that supports 'std' flag
Based on the HAL from stm32wl, the peripheral driver has been
modified to fit into embassy, using the embassy APIs, providing
operation of the radio peripheral.
The initial version does not offer any async APIs, but the example
shows how the radio IRQ can be used to perform async TX of the radio.
