1054: riscv fixes r=lulf a=swolix
With these changes I can run embassy on our RISC-V processor, please consider merging this, feedback is very welcome.
I don't fully understand the code in the executor, but I have implemented a critical section by globally disabling interrupts, which means the wfi inside the critical section will hang the whole thing.

Add "rtos-trace-interrupt" feature flag on embassy-macros and enable it
for embassy-executor, to ensure that the interrupt::take! macro can be
used without depending on embassy-executor.
This was used in the past for reexporting the macros from drogue-device,
which is no longer using it.
Also, it is a pain to support, so we don't want it.
- 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`.
742: Only 1 argument in embassy::main when there is no HAL r=Dirbaio a=jbeaurivage
There is a slight mistake in an error message from `[embassy::main]` macro. When there is no HAL specified, `main` should take only one argument.

The normal `spawn()` methods can be called directly by the user, with arbitrary hand-implemented futures.
We can't enforce they're only called with `async fn` futures. Therefore, make these
require `F: Send`, and add a "private" one only for use in the macro, which can enforce it.
Fixes a new opaque type error in the task macro.
Full error is "opaque type's hidden type cannot be another opaque type from the same scope".
This got disallwed by the lazy-TAIT PR: https://github.com/rust-lang/rust/pull/94081
Sadly there's now some weird type inference errors with pre-lazy-TAIT
nightlies, so support for those is dropped.
* 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
Fixes#18
Syn considers doc comments to be attributes, so forwarding those fixes the issue.
It's probably a good idea to forward most attributes anyway.
Currently this looks up the frequency in the global singleton that must
be initialized by the per-chip RCC implementation. At present, this is
only done for the L0 family of chips.
* Moves the tim2-specific code into macro which always uses TIM2
* For peripherals without clock specified, attempt to locate enable and
reset registers in the RCC block matching the peripheral name. This
could be useful for peripherals where deducing the clock name might
not be feasible, but it remains to be tested with more chip families
to see if it is sufficiently accurate.
Modify init function to return a Clock instance defined by a per-chip
SystemClock type and use this in macro setup
A proof of concept implementation for STM32 L0 chips.
This allows using embassy::main macros for STM32 devices that have the
clock setup logic.
