[PATCH v3 02/14] ArmPkg/ArmMmuStandaloneMmLib: Update to match ArmMmuLib

["Bret Barkelew" <bret@corthon.com>]

From: Bret Barkelew <brbarkel@microsoft.com>

Drop switch from the custom "StandaloneMmMmuLib" class to the
more generic "ArmMmuLib" class and add the missing functions
to fulfill that interface.
