This introduces a `Pender` struct with enum cases for thread-mode, interrupt-mode and
custom callback executors. This avoids calls through function pointers when using only
the thread or interrupt executors. Faster, and friendlier to `cargo-call-stack`.
`embassy-executor` now has `arch-xxx` Cargo features to select the arch and to enable
the builtin executors (thread and interrupt).
- Allows classes to handle vendor requests.
- Allows classes to use a single handler for multiple interfaces.
- Allows classes to access the other events (previously only `reset` was available).
1024: stm32/adc: Remove voltage and temperature conversions r=Dirbaio a=GrantM11235
The current conversion utilities are confusing and a bit of a footgun. (Two out of the three examples got it wrong! They didn't measure vref at all, so all the conversions are completely wrong if vcca isn't 3.3v)
I think we should eventually have some sort of conversion utilities in the HAL, but for now I think it is best to just remove it and let the users do their own math.

1025: Implement I2C timeouts, second attempt r=Dirbaio a=chemicstry
This is an alterrnative to #1022 as discussed there.
Timeouts are implemented using suggested `check_timeout: impl Fn() -> Result<(), Error>` function, which does not depend on `embassy-time` by default and is a noop for regular I2C.
This also adds `time` feature like in `embassy-nrf` to enable `embassy-time` dependencies. While at it, I also gated some other peripherals that depend on `embassy-time`, notably `usb` and (partially) `subghz`.
`TimeoutI2c` is currently only implemented for i2cv1, because i2cv2 has additional complications:
- Async methods still use a lot of busy waiting code in between DMA transfers, so simple `with_timeout()` will not work and it will have to use both types of timeouts. It could probably be rewritten to replace busy waits with IRQs, but that's outside the scope of this PR.
- I2C definition `I2c<'d, T, TXDMA, RXDMA>` is different from i2cv1 `I2c<'d, T>` making it hard to share single `TimeoutI2c` wrapper. A couple of options here:
- Duplicate `TimeoutI2c` code
- Add dummy `TXDMA`, `RXDMA` types to i2cv1 considering that in the future it should also support DMA

It was only useful for doing #[embassy_executor::main(config = "config()")]`. Now that
it's gone, it makes more sense to build the config in main directly.
858: embassy-stm32: Simplify time r=Dirbaio a=GrantM11235
- Remove unused `MilliSeconds`, `MicroSeconds`, and `NanoSeconds` types
- Remove `Bps`, `KiloHertz`, and `MegaHertz` types that were only used
for converting to `Hertz`
- Replace all instances of `impl Into<Hertz>` with `Hertz`
- Add `hz`, `khz`, and `mhz` methods to `Hertz`, as well as
free function shortcuts
- Remove `U32Ext` extension trait

- Remove `U32Ext` extension trait
- Move Interrupt and InterruptExecutor from `embassy` to `embassy-cortex-m`.
- Move Unborrow from `embassy` to `embassy-hal-common` (nothing in `embassy` requires it anymore)
- Move PeripheralMutex from `embassy-hal-common` to `embassy-cortex-m`.
Following the project's decision that "leak unsafe" APIs are not marked as "unsafe",
update PeripheralMutex to accept non-'static state without unsafe.
Fixes#801
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.
The initial closure is not actually called in the interrupt, so this is
illegally sending non-Send futures to the interrupt.
Remove the closure, and return a SendSpawner instead.
Includes the addition of a `dbgmcu!(...)` macro table which currently takes
the form of
(cr, $fn_name:ident)
where `$fn_name` is something like `set_dbgsleep_d1` etc.
The method is unsafe, since it's performing unsafe PAC operations.
Two examples modified to demonstrate its usage.
