Add Bit mask to numeric/one of opcode to set correctly Flags for Bit Field.
VfrSyntax.g: Set "LFlags &= EDKII_IFR_DISPLAY_BIT" before "LFlags |= (EDKII_IFR_NUMERIC_SIZE_BIT & (_GET_CURRQEST_VARSIZE()));"
VfrFormPkg.h: update "if (LFlags & EFI_IFR_DISPLAY)" with "if (LFlags & EDKII_IFR_DISPLAY_BIT)" in SetFlagsForBitField()
