DynamicTablesPkg/Acpi: Add LoongArch64 MADT generator

Add a MADT generator for LoongArch64 Core, LIO, HT, EIO, MSI, BIO,
and LPC interrupt controllers. Validate required objects, structure
versions, identifiers, reserved flags, invalid physical CoreIds,
address ranges, MSI vector ranges, and table size before writing the
ACPI table.

Support MADT revisions from ACPI 6.5, where the LoongArch64 interrupt
controller structures were introduced, through ACPI 6.6.
