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.
