MdeModulePkg Variable: Move VariableLock install into SmmVariableReady().
VariableLock in VariableSmmRuntimeDxe.c is installed in EntryPoint now.
It works based on SMM variable handler by SMM communication with
payload buffer. But the payload buffer and SMM variable handler will
be not ready in EntryPoint before SmmVariableReady() call back.
VarCheck in VariableSmmRuntimeDxe.c has the same issue,
so move VarCheck install into SmmVariableReady() also.
