[Patch v2 2/4] CryptoPkg/Library/Include: Allow CPU specific defines to be predefined

["Michael D Kinney" <michael.d.kinney@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3308

The EDK II Build Specifications do not restrict the set of
CPU architectures that can be supported.  Remove places in
the EDK II that assume a fixed set of CPU architectures.

Update SIXTY_FOUR_BIT and THIRTY_TWO_BIT defines in the
CryptoPkg to allow one of them to be predefined on the EDK II
build command line using /D flag or in DSC file [BuildOptions]
sections.
