Now that we have the prerequisite functionality available in ArmMmuLib,
wire it up into ArmSetMemoryRegionNoExec, ArmClearMemoryRegionNoExec,
ArmSetMemoryRegionReadOnly and ArmClearMemoryRegionReadOnly. This is
used by the non-executable stack feature that is configured by DxeIpl.
NOTE: The current implementation will not combine RO and XP attributes,
i.e., setting/clearing a region no-exec will unconditionally
clear the read-only attribute, and vice versa. Currently, we
only use ArmSetMemoryRegionNoExec(), so for now, we should be
able to live with this.
