  [GTK][WPE] Add more WPE related trace points to better understand the graphics pipeline
https://bugs.webkit.org/show_bug.cgi?id=277412

Reviewed by Miguel Gomez.

Add new WPE specific trace points that help us understand the graphics
pipeline, starting from DRM vblank signal (capture by sysprof) until
composition starts/ends for a frame.

Based on a patch from Alejandro G. Castro, refactored to avoid changing
any of the existing enum values - which would be problematic for the Apple
ports.

No new tests - doesn't affect non-glib ports.
