ShellPkg: Update Acpiview PPTT parser to ACPI 6.4

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.

Mantis ID for removing PPTT type 2 structure:
2072 (https://mantis.uefi.org/mantis/view.php?id=2072)
