MdeModulePkg/VarCheckHii: Enhance VarCheckHiiLib to support bit check

V3:
(1) Reset QuestionStoredInBitField to FALSE at end opcode(EFI_IFR_END_OP)
(2) Fix typo and format issues(line alignment for debug print message
and value assignment...)

V2:
(1)Remove the VarOffsetBitLevel/StorageWidthBitLevel to reduce the final
VarCheckBinSize and update the implementation accordingly.
(2)Update the VAR_CHECK_HII_REVISION
(3)Refine the Debug message and function comments,like update oneof",
"checkbox", "numeric" to "OneOf", "CheckBox", "Numeric".

VarCheckHiiLib check the value set to storage based on the possible value
listed in the vfr file. Since we have enhanced vfr to support Question
value stored in bit field, so now enhance VarCheckHiiLib to support bit
field check.
