[patch 2/3] MdeModulePkg/BMMUiLib: Signal event when enter/exit setup menu

[Dandan Bi <dandan.bi@intel.com>]

These changes are to support notify callbacks when enter/exit
setup menu, since some driver may need to hook setup enter/exit
points to do something.

We will signal setup enter/exit events for all setup menu
enter/exit cases.Then the module which pay attention to these
events can execute the callback.
