arm64: entry: Add entry and exit functions for debug exceptions

Browse source

Move the `debug_exception_enter()` and `debug_exception_exit()`
functions from mm/fault.c, as they are needed to split
the debug exceptions entry paths from the current unified one.

Make them externally visible in include/asm/exception.h until
the caller in mm/fault.c is cleaned up.
