- 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`.
