Reviewed by Devin Rousso and BJ Burg.

Screenshots are taken when a composite occurs to populate the screenshots timeline. Composites do not occurs for
the same types of updates in WebKitLegacy as they do in WebKit2. Due to this, the timeline currently appears
broken on WebKitLegacy targets. Until we can do the work in webkit.org/b/251113 to support WebKitLegacy, we
instead will disable the Screenshots timeline when inspecting WebKitLegacy targets (the "Page" debuggable type,
as opposed to the WK2 "Web Page" debuggable type).
