ArmVirtPkg: move all platforms to MdePkg/ BaseMemoryLib implementations 

The BaseMemoryLibStm implementation under ArmPkg/ is being deprecated,
in favor of the generic versions under MdePkg, now that ARM and AARCH64
support has been added to both the generic C version (BaseMemoryLib) and
the accelerated version (BaseMemoryLibOptDxe). The latter uses unaligned
accesses and special cache maintenance instructions, and can therefore
not be used when the MMU is off.

So move to BaseMemoryLibOptDxe for the DXE phase and later, and to the
generic BaseMemoryLib before that.
