ArmPkg/ArmMmuLib: add PEI specific version of ArmMmuLib This introduces a special version of ArmMmuLib for PEIMs that takes care only to perform cache maintenance on the live entry replacement routine if the module is not executing in place. Not only is such cache maintenance unnecessary in that case, it may be actively harmful on some systems that fail to tolerate cache maintenance operations on NOR flash regions.

ArmPkg/ArmMmuLib: base page table VA size on GCD memory map size As reported by Eugene, the practice of sizing the address space in the virtual memory system based on the maximum address in the table passed to ArmConfigureMmu() is problematic, since it fails to take into account the fact that the GCD memory space may be extended at a later time, both for memory and for MMIO. So instead, choose the VA size identical to the GCD memory map size, which is based on PcdPrePiCpuMemorySize on ARM systems.
