Use XtalClock as UART source and adapt interrupt binding

[SergioGasquez]

• Use XtalClock as UART source when possible
• Update interrupt bindings

Testing

I've tried flashing a few targets (C6 and H2) with the generated stubs and they were working fine.

I've created https://github.com/SergioGasquez/espflash/tree/feat/test-stubs updating all the stubs ~and once https://github.com/esp-rs/espflash/pull/625 is merged, I'll run espflash HIL CI on that branch so we can test all the targets with new stubs.~

Here is the HIL run with the test stubs: https://github.com/esp-rs/espflash/actions/runs/8749962162
