- Move typelevel interrupts to a special-purpose mod: `embassy_xx::interrupt::typelevel`.
- Reexport the PAC interrupt enum in `embassy_xx::interrupt`.
This has a few advantages:
- The `embassy_xx::interrupt` module is now more "standard".
- It works with `cortex-m` functions for manipulating interrupts, for example.
- It works with RTIC.
- the interrupt enum allows holding value that can be "any interrupt at runtime", this can't be done with typelevel irqs.
- When "const-generics on enums" is stable, we can remove the typelevel interrupts without disruptive changes to `embassy_xx::interrupt`.
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
