1f746e0939 Remove the authors field from Cargo.tomls
It currently contains whoever was first to write some code for the crate,
even if many more people have contributed to it later.

The field is "sort of" deprecated, it was made optional recently:
https://rust-lang.github.io/rfcs/3052-optional-authors-field.html

Due the the reasons listed there I believe removing it is better than
setting it to generic fluff like "The Embassy contributors".

5085100df2 Add embassy-cortex-m crate.
- 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.

1599009a4f executor: "send-spawn is OK if the args are Send" only holds for async fn futures.
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.

408617266e Update Rust nightly.
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.

53e66a383f Forward attributes to generated task function
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.

952f525af5 Provide a way for a peripheral to query its clock frequency
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.

0a9022d59f Enable timer clock in RCC on timer start
* 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.

9586365b07 Pass config directly to chip specific configure function
This removes the need to duplicate the configuration for each individual
chip, but will instead pass on the configuration specified in the config
attribute.

Update nrf, stm32, rp macros with passing the config to a per-chip
configure function which assumes the appropriate configuration to be
passed to it.

To demonstrate this feature, the stm32l0xx clock setup and RTC is added which exposes
clock configuration different from stm32f4xx (and has a different set of timers and HAL APIs).

retain the existing behavior.
