core/cortex-m: Allow boards to override interrupt priorities
A lot of code in common/ and elsewhere use DECLARE_IRQ() to designate an
interrupt handler, and set a priority.
This CL makes it possible for board code to override the priorities set
in common code via DECLARE_IRQ(), in case of special considerations.
BUG=b:266832220
TEST=./util/compare_build.sh -b {discovery,munna}
