Ard Biesheuvel b05523a4e9 ArmPkg/ArmMmuLib: Introduce region types for RO/XP WB cached memory
To prepare for the enablement of booting EFI with the SCTLR.WXN control
enabled, which makes all writeable memory regions non-executable by
default, introduce a memory type that we will use to describe the flash
region that carries the SEC and PEIM modules that execute in place. Even
if these are implicitly read-only due to the ROM nature, they need to be
mapped with read-only attributes in the page tables to be able to
execute from them.

Also add the XP counterpart which will be used for all normal DRAM right
at the outset.
