Since bug 1653737 Webrender wants to have an estimate for the next presentation time. Currently this is derived from a hardcoded 60Hz refresh rate - lets add a simple heuristic to provide a better guess when using the Wayland Vsync source, so we get better results on non-60Hz displays.
For now, just do that based on frame callbacks - we can improve it using the presentation time protocol later.

This implements a very simplistic estimate of the refresh interval.
While not very accurate, it should sligtly improve frame timing on
non-60Hz screens and could prove handy in other situations.
Once the Wayland Vsync source is propperly wired up we can improve
it - potentially with the presentation time protocol or with some
smarter logic.
