ArmPkg/ArmMmuLib: AARCH64: add support for modifying only permissions
Since the new DXE page protection for PE/COFF images may invoke
EFI_CPU_ARCH_PROTOCOL.SetMemoryAttributes() with only permission
attributes set, add support for this in the AARCH64 MMU code.
Move the EFI_MEMORY_CACHETYPE_MASK macro to a shared location between
CpuDxe and ArmMmuLib so we don't have to introduce yet another
definition.
