DynamicTablesPkg: Update MADT generator for ACPI 6.5 

The ACPI 6.5 specification updates the MADT table to add
a new field to GICC for specifying the TRBE interrupt and
also adds support for Online Capable flag to the GICC flags.

The Online Capable flags should be passed transparently
through as specified in the CM_ARM_GICC_INFO.Flags field
and only require the MADT table revision to be setup to
6 to reflect the ACPI 6.5 specification.

The TRBE field needs to be appropriately setup in the
GICC structure.

Therefore, update the MADT generator to reflect the
above updates required for supporting ACPI 6.5
