CryptoPkg: BaseCryptLib: Add unit tests (Host and Shell based)

This adds a new INF for BaseCryptLib suitable for
host based environments. It adds a host based unit test for
BaseCryptLib that can also be built as a shell based Unit Test.

In addition, this also adds a UnitTestHostCrtWrapper.c file, which provides
some of the functionality not provided by the default host based unit test
system that OpenSSL expects. This is used by UnitTestHostBaseCryptLib, a
version of the BaseCryptLib meant specifically for host based unit testing.
