The compiler (visual studio) may optimize some explicit strcmp call
in openssl source to use the intrinsic memcmp call.
In CrtLibSupport.h, we just use #define to mapping memcmp to
CompareMem API. So in Link phase, this kind of intrinsic optimization
will cause the "unresolved external symbol" error. For example:
OpensslLib.lib(v3_utl.obj) : error LNK2001:
unresolved external symbol _memcmp
This patch will keep the memcmp mapping, and provide extra Intrinsic
memcmp wrapper to satisfy the symbol link.

Moving the header files for openssl and CRT wrappers to the private
include section, since these files should be referenced by CryptoPkg
internally. This update was supported by new [Includes.Common.Private]
setting in Package DEC file.
The external consumer modules should only use the interfaces defined
in BaseCryptLib.h to access crypto functions. This change will be
helpful to immediately detect any illegal direct reference to internal
openssl headers.
The Perl script "process_files.pl" was also updated to reflect the new
private include path.
