Can we use OPENSSL_EXPORT from "openssl/base.h"? Seems like it would come in handy, so we wouldn't need duplicate definitions in both rust_wrapper.hs

[justsmth]

Is that intended for use outside the library? It might work if we define BORINGSSL_IMPLEMENTATION and BORINGSSL_SHARED_LIBRARY prior to its include.

hmm I was under the impression that these were already defined if we built with AWS-LC.

Not a blocker though, just curious if it was reusable
