921780e6bf Make interrupt module more standard. 
- 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`.

Merge #1370 
1370: stm32/i2c: fix races when using dma. r=Dirbaio a=xoviat

This change addresses two races:

1. It removes the `chunks_transferred` state variable that is modified inside the interrupt. Analysis of the code reveals that the only time the waker can be woken is when `chunks_transferred` is incremented. Therefore, waking is enough to signal the `poll_fn` that the `chunks_transferred` has incremented. Moving to `remaining_len` clarifies the code, since there is no need to track how many chunks are remaining.
2. It moves the start of the transfer until after the waker is registered, which could theoretically occur if the clock speed is very low, but probably never would even if this wasn't fixed.

There is another race that I noticed: between writes the waker may not yet be registered. In that case, the code would simply be stuck and the `poll_fn` would never be woken. There is no way to resolve this without broadening the scope of the analysis, and this will likely never occur.
