DynamicTablesPkg: Rename GicCToken field in Processor Hierarchy Info

Browse Source 
The GicCToken field in the CM_ARM_PROC_HIERARCHY_INFO structure is
a reference to the associated object which has the corresponding
ACPI Processor ID, e.g. for Arm systems this is a reference to the
CM_ARM_GICC_INFO object.
For other architecture this may be a reference to a similar object
that has the ACPI Processor ID.

Therefore, rename the GicCToken field to a more generic name like
AcpiIdObjectToken.

Correspondingly also update the following modules to reflect the
changes introduced by this renaming:
 - PPTT generator
 - SSDT CPu topology generator
 - ConfigurationManagerObjectParser.
