The ACPI 6.4 specification added a new 'Cache ID' field to the PPTT Cache (type
1) Structure as well as removed the previously deprecated PPTT ID (type 2)
structure. These changes should be incorporated into edk2 to support the latest

The changes that need to be made to accommodate the latest ACPI 6.4 spec are:
- Remove the PPTT type 2 structure from Acpi64.h
- Update the Acpiview PPTT parser to add 'Cache ID' and remove type 2
- Update the DynamicTablesPkg PPTT generator with the 'Cache ID' field and
remove the type 2 structure.
