Ard Biesheuvel 4d9a4f62cf ArmPkg/ArmLib MMU: add functions to set/clear RO and XN bits on regions
Use the refactored UpdateRegionMapping () to traverse the translation
tables, splitting block entries along the way if required, and apply
a mask + or on each to set or clear the PXN/UXN/XN or RO bits.

For now, the 32-bit ARM versions remain unimplemented.
