ArmPlatformPkg: Introduce ArmPlatformGlobalVariableLib
This library hides where the 'XIP' Global Variable are located in the memory.
It is expected the Sec/PrePi modules define the Global Variable area through
the GlobalVariable HOB.
The ArmPlatformGlobalVariableLib library allows access to global variables by
their offsets in this region.
