CryptoPkg: Add Null instance of the BaseCryptLib class

https://bugzilla.tianocore.org/show_bug.cgi?id=2257 Add a Null instance of the BaseCryptLib class. This lib instance can be used as a template for new implementations of the BaseCryptLib class and can also be used to reduce CI build times for build checks that depend on the BaseCryptLib class.
