arm64: mte: Add Memory Tagging Extension documentation

Browse source

Memory Tagging Extension (part of the ARMv8.5 Extensions) provides
a mechanism to detect the sources of memory related errors which
may be vulnerable to exploitation, including bounds violations,
use-after-free, use-after-return, use-out-of-scope and use before
initialization errors.

Add Memory Tagging Extension documentation for the arm64 linux
kernel support.
