UefiCpuPkg/Cpuid: Fix GCC build error 

define PRINT_BIT_FIELD(Variable, FieldName) \
  Print (L"%5a%42a: %x\n", #Variable, #FieldName, \
  ##Variable.Bits.##FieldName);

The above definition in UefiCpuPkg/Application/Cpuid/Cpuid.c
will cause GCC build error.

Fix it with:

define PRINT_BIT_FIELD(Variable, FieldName) \
  Print (L"%5a%42a: %x\n", #Variable, #FieldName, \
  Variable.Bits.FieldName);

The '.' has its origin meaning as a member operator in the define
statement. Thus, the token-pasting operator '##' is not necessary here.
