SecurityPkg: Tcg2Smm: Added support for Standalone Mm

https://bugzilla.tianocore.org/show_bug.cgi?id=3169

This change added Standalone MM instance of Tcg2. The notify function for
Standalone MM instance is left empty.

A dependency DXE driver with a Depex of gEfiMmCommunication2ProtocolGuid
was created to indicate the readiness of Standalone MM Tcg2 driver.

Lastly, the support of CI build for Tcg2 Standalone MM module is added.
