ArmPlatformPkg/PrePeiCore: Reserve some memory on the top of the stack for Global Variables in XIP code
The size of this memory is controlled by a PCD. The Global Variable in this regsion are defined by their offset.
This memory region can be use to store the PEI Services Table Pointer.
Update the PeiServicesTablePointerLib to use this region instead of PcdPeiServicePtrAddr.
