  [GTK][WPE] Add more composition related signposts
https://bugs.webkit.org/show_bug.cgi?id=278963

Reviewed by Adrian Perez de Castro.

Add detailed signposts to understand where time is spent in
CoordinatedBackingStoreTile::swapBuffers - as preparation to investigate
different tile updating strategies.

Furthermore add some more signposts to ThreadedCompositor, to better
understand the trace scope 'FrameComposition'.

Doesn't affect any tests.
