[PATCH v2 0/6] Add DxeMmUnblockMemoryLib Interface and Usages

[Kun Qin]

The interface proposed in this patch series intends to provide an
abstraction layer for DXE drivers to request certain memory regions to be
accessible from inside MM environment that applies total memory blockage.

The usage in VariableSmmRuntimeDxe to support runtime variable cache is
included in this patch series.

The usage in MM instance of Tcg2 to unblock NVS region is added after
separating the module into Tcg2Acpi and Tcg2 MM to support StandaloneMm.
