MdeModulePkg/Variable: Consume Variable Flash Info

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3479

Updates VariableRuntimeDxe, VariableSmm, and VariableStandaloneMm
to acquire variable flash information from the Variable Flash
Information library.

Note: This introduces a dependency on VariableFlashInfoLib in these
modules. Therefore, a platform building the variable modules must
specify an instance of VariableFlashInfoLib in their platform build.
