Rename WebMediaPlayerImpl::Repaint() to WebMediaPlayerImpl::InvalidateOnMainThread().

Documentation is added to highlight that using this path isn't ideal for normal video frame updates.

In addition, TODOs are added to the few InvalidateOnMainThread() call sites that are (ab)used for repainting controls.
