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`.

482389a691 Own the sequence buffer
This approach owns the sequence buffers which, while introducing an extra move, it eliminates the need to guard the lifetime of the sequence buffer. Given ownership, the buffer will be retained until the PWM sequence task is stopped.

47aeab152f PWM WS2812B example and per sequence config
Demonstrates how to set the colour of a WS2812B to blue using PWM, and the use of multiple sequences along with their own config. This required an API change.

c9f29534d6 Stop PWM before assigning the new sequence
I had introduced a small bug in my last PR where I assigned the sequence before stopping the PWM. I now stop the PWM before doing that now.

Also, corrected a math comment.

48afef28a0 Strengthen the borrow
The start method is now safe. Because it has the potential of borrowing the sequence and mutating itself, the sequence must outlive the Pwm struct.

7598b8a40f Permit many sequences to be passed
Sequences are now passed in via the start method to avoid having to stop the PWM and restart it. Sequences continue to be constrained with the same lifetime of the Pwm object itself. The pwm_sequence example has been extended to illustrate multiple sequences being passed around.
