GLES: Free textures on device lost, and unsubmitted step data at exit

- The texture and fragment test caches dropped their GLRTexture objects on
  DeviceLost without queueing them for deletion, leaking them on every
  Android background/resume. The deleter already skips the GL calls when
  the context is gone.
- GLRenderManager::ThreadEnd cleared unsubmitted init and render steps
  without freeing the data they own. Run them through the dry run instead,
  which now also frees stereo matrices and shader code.
