CrOS: Plumb through vsync info to compositor on EGL stacks
Uses EGL_CHROMIUM_sync_control (a subset of GLX_OML_sync_control) to calculate refresh rate and when refreshes occur. This CL factors out common code from the GLX_OML_sync_control implementation.
BUG=none
TEST=by hand on stumpy, daisy, and desktop
