DynamicTablesPkg: Add LoongArch64 CM namespace header

Define a LoongArch64 Configuration Manager namespace for MADT data.
The objects describe table-wide settings and the Core, LIO, HT, EIO,
MSI, BIO, and LPC interrupt controllers.

Use AcpiProcessorUid for the processor identity matched to an AML _UID,
and model MAX_UINT32 as the invalid physical CoreId. Expose each
ACPI-defined PIC structure Version through its matching CM object.
Currently, ACPI defines only version 1.
