CryptoPkg/IntrinsicLib: Fix possible unresolved external symbol issue

Browse Source 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1089

This is for the upcoming upgrade to OpenSSL_1_1_1b

Compiler optimization(Visual Studio) may automatically use _ftol2
instead of some type conversion. For example:

 OpensslLib.lib(drbg_lib.obj) : error LNK2001:
    unresolved external symbol __ftol2

This patch add _ftol2 function for the compiler intrinsic.
