Subject: [PATCH] Tracing: Add tooltip to category labels in analyzer timelines

This is especially useful for longer names that often get elided in the
Perf Profiler and the new Chrome Trace Format Visualizer.

It uses a dummy button to show the same tooltip style as the buttons
while not having to import QtQuick.Controls.Private.
