DynamicTablesPkg: Add ACPI 6.3 SPE support to MADT generator

Browse Source 
The Dynamic Tables Framework now supports generating Multiple APIC
Description Table (MADT) revision 5 for ARM platforms while maintaining
backward-compatibility with ACPI 6.2.

The relevant change is the enablement of the Statistical Profiling
Extension (SPE).
