Wire up didPaint, didLayout, didScroll, didRecalculateStyle instrumentation hooks in PageAgentProxy for paint rect visualization. setShowPaintRects/setShowRulers need forwarding from UIProcess to all WebProcesses. Overlay rendering happens in WebProcess (part of compositor), so PageAgentProxy can operate on InspectorOverlay directly. But the setting must be forwarded and replayed to new processes.
