Gracefully handle screen.orientation access over unsupported frames.
WebLocalFrame-hosted LocalFrames install screen orientation support;
WebPagePopup-hosted ones reasonably don't. The window of the latter
kind are accessible in non-production builds, so correctly handle
any attempted access to screen.orientation for these.
