MdeModulePkg/Core: Fix build error with old Visual Studio 

The build error is introduced by following check in:
  2930ef9809
  235a4490c8

The Visual Studio older than 2015 doesn't support constant integer
in binary format (0bxxx). This patch changes them to BIT macro to
fix it. This patch also cleans up coding style about unmatched
comment for return value.
