DynamicTablesPkg: Add dynamic PPTT table generation support

The PPTT generator uses the configuration manager protocol to
obtain information about platform's processor topology and caches.
This data is then used to generate the PPTT table.

The table generator supports ACPI 6.3, PPTT table revision 2.

The dynamic PPTT generator also carries out extensive input
validation which includes cycle detection and MADT-PPTT
cross-validation. A number of architectural compliance checks
are also performed.
