Enable MTE support
Enable MTE support by adding memory tag option in Makefile
This option is available only when ARMv8.5-MemTag is implemented
MTE options are added in latest clang and armclang compiler which
support below options:
for clang <version 11.0.0>
1. -march=arm8.5-a+memtag
2. -fsanitize=memtag
for armclang <version 6.12>
1. -march=arm8.5-a+memtag
2. -mmemtag-stack
Set the option SUPPORT_STACK_MEMTAG=yes to enable memory stack tagging.
