lib: prefer CURL_SHA256_DIGEST_LENGTH over the unprefixed name
Already used in `vtls.h`. Prefer this curl-namespaced name over the
unprefixed `SHA256_DIGEST_LENGTH`. The latter is also defined by TLS
backends with a potential to cause issues.

Also stop relying on externel headers setting this constant. It's
already defined in `vtls.h` on curl's behalf, do this also for `lib`.

Cherry-picked from #14495
Closes #14513
