[Media] Use nanoseconds as MaximumTimeScale
https://bugs.webkit.org/show_bug.cgi?id=190631
1e9 is a much more useful timescale than the previous one 2^31-1.
Unlike 2^31-1, which is a prime number, nanosecond scale is pretty
common among some formats like WebM and frameworks like GStreamer
where base 10 timescale is common... and it's those big timescales the
ones that are usually scaled up to MaximumTimeScale.
