MdeModulePkg: Define the VarCheckPolicyLib and SMM interface
https://bugzilla.tianocore.org/show_bug.cgi?id=2522
VariablePolicy is an updated interface to
replace VarLock and VarCheckProtocol.
This is an instance of a VarCheckLib that is backed by the
VariablePolicyLib business logic. It also publishes the SMM
calling interface for messages from the DXE protocol.
