arch/xtensa/espressif: Add IRQ lookup by interrupt handle.

Browse source 
Add esp_get_irq() to retrieve the IRQ associated with an interrupt
handle.

This allows the ESP OS abstraction to recover the IRQ when freeing an
interrupt from its handle.

The corresponding change in esp-hal-3rdparty is required to use this
API when freeing interrupts.
