* fix interrupt handling for the ln882h

- all GPIOS can generate interrupts
- added calls to NVIC_SetPriority/NVIC_EnableIRQ/NVIC_DisableIRQ

* fix clang formatting error

* only call NVIC_DisableIRQ if no other gpio is using an interrupt

* fix (again) clang-format errors

* add IRQ capability on all pins

* don't bother with NVIC_DisableIRQ

* use pin->gpio instead of interruptNumber, use macro GPIO_GET_PORT for clarity

* Mark interrupts as supported for the LN882H

-## LibreTuya is now LibreTiny! 🎉

-We have [renamed the project](https://github.com/kuba2k2/libretiny/issues/92) to LibreTiny, also marking the very first v1.0.0 release, along with a huge structure refactor. While some care has been taken to ensure that things don't break, you may still need to update some references in your code to use the new name.
