Improve the system tracing points
​https://bugs.webkit.org/show_bug.cgi?id=169790

Reviewed by Zalan Bujtas.

Use a more cohesive set of system trace points that give a good overview of what
WebKit is doing. Added points for resource loading, render tree building, sync messages
to the web process, async image decode, WASM and fetching cookies.

     8        Use a more cohesive set of system trace points that give a good overview of what
     9        WebKit is doing. Added points for resource loading, render tree building, sync messages
     10        to the web process, async image decode, WASM and fetching cookies.
