Marc Moisson-Franckhauser 618e6a1f21 ShellPkg/AcpiView: HMAT Parser 
Bugzilla: 3045 (https://bugzilla.tianocore.org/show_bug.cgi?id=3045)

Add a new parser for the Heterogeneous Memory Attribute Table. The
parser also validates some fields for this table.

The HMAT table is used to describe the memory attributes such as memory
side cache attributes and bandwidth and latency details related to
memory proximity domains. The info in the HMAT table can be used by an
operating system for optimisation.
