MdeModulePkg/SetupBrowser: Handle questions with Bit VarStore 

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=545

For oneof/numeric/CheckBox(storage can be Bit VarStore)
If the question value can be updated and shown correctly
in UI page, we need do enhancements in following cases:
1. Parse the Ifr data to get the bit VarStore info correctly.
2. Set/get value to/from bit VarStore correctly.
