ArmPlatformPkg/ArmVExpressPkg: Added support to differentiate ARMv8 FVP variants

Browse Source 
There are three FVP variants for the Base and Foundation models:
- model with GICv2 legacy memory map (same location as the Versatile Express model)
- model with GICv2 and Base model memory map
- model with GICv3 and Base model memory map

The new code detects the variants to load the appropriate device tree.
