This was a dead API. Nothing ever used it, it wasn't exposed in any
API headers. It never appeared in documentation. It's not
particularly clear why a Zephy app would want to hook
architecture-specific exceptions instead of simply using the portable
error framework anyway. And it's not supported by asm2. Delete.

This cleans up the exception handling by removing the table declaration
from xtensa_intr_asm.S, and removing the unused
_xt_set_exception_handler() function.

The Xtensa port was the only one remaining to be converted to the new
way of connecting interrupts in Zephyr. Some things are still
unconverted, mainly the exception table, and this will be performed
another time.
Of note: _irq_priority_set() isn't called on _ARCH_IRQ_CONNECT(), since
IRQs can't change priority on Xtensa: while the architecture has the
concept of interrupt priority levels, each line has a fixed level and
can't be changed.
