CryptoPkg: Clean-up CRT Library Wrapper.
Browse files Browse the repository at this point in the history 
Cleaning-up CRT Library Wrapper for the third-party cryptography
library building. The changes includes
1. Rename OpenSslSupport.h to CrtLibSupport.h for future alternative
   crypto provider support.
2. Remove all un-referenced CRT APIs and headers.

(NOTE: More cleans-up could be possible after OpenSSL integrate the
      extra PR request: openssl/openssl#2961)
