Structural changes to better support Package Manager builds.

- A #define is added to include/openssl/base.h (this needs to be added to the vendoring script).
- links are added to CgRPC/include to point to other directories of include files.
- a modulemap is added to CgRPC/include to avoid confusion caused by the new directory links.
