Today, the internal frame dropper in libvpx vp8 encoder is enabled or disabled based on video or screen content. This is then expected to match up with screenshare vs default temporal layers implementation. This cl makes libvpx query the temporal layers implementation as well, breaking this implicit dependency and allows frames to be dropped if default temporal layers is used with screen content.
