Bugzilla: 3697 (https://bugzilla.tianocore.org/show_bug.cgi?id=3697)
Update the Acpiview PPTT parser to use Acpi64.h. As part of the changes,
remove support for parsing PPTT type 2 ID structure.
Signed-off-by: Chris Jones <christopher.jones@arm.com>

Notes:
v2:
- Changed PPTT ID error message to say "removed" instead of "deprecated".
