Subject: [PATCH] chrome: Unlatch download override notification on fullscreen exit update

When a download begins while in fullscreen, notify_overridden_ was
previously sticky and kept params_.has_download pinned to true for all
subsequent updates and re-shows. Because GetInstructionTextForType()
omits the origin whenever has_download is true, the site origin was
permanently suppressed after any download occurred during fullscreen.

This CL unlatches notify_overridden_ when !params.has_download or when
the origin changes, ensuring the origin is restored once the download
notification clears.
