feat: add coraza_is_response_body_processable() API

Expose IsResponseBodyProcessable() through the C API so connectors
can skip response body processing when SecResponseBodyAccess is Off
or the Content-Type doesn't match SecResponseBodyMimeType.

Returns 1 if the body should be processed, 0 otherwise.
Must be called after coraza_process_response_headers().
