feat(ethos-n): add NPU support in fiptool

Add platform specific Makefile to add UUIDs and command options
for the Arm(R) Ethos(TM)-N NPU firmware binary and certificate
data to the FIP so that the TF-A's BL2 can later be used to load
the Arm(R) Ethos(TM)-N NPU firmware binary into memory and verify
its integrity.

Add separate driver specific include header file for the
Arm(R) Ethos(TM)-N NPU images containing UUIDs and command options
to make it easy to port the FIP support to other platforms.
