From: Michael Kubacki <michael.kuba...@microsoft.com>

Commit `b71f2bd` introduced a couple build errors in
VariableWritelib. This change adds the SMM Services Table (`gSmst`)
and MM Services Table (`gMmst`) calls needed to register the
protocol notify in the Traditional and Standalone MM services
constructors.
