Qin Long 5d7a1d63c0 CryptoPkg: Fix possible unresolved external symbol issue.
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.
