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.
