Add a performance test for launching DocumentsUI. The test launches the DocumentsUI as picker, then waits until the main thread idles, which guarantees that roots are loaded and UI rendered. It confirms, that the recent system cache improves cold start performance by around 24% on my configuration (from 1685ms to 1357ms). Bug: 27370274 Change-Id: I738202ea434a7bfe7080fc0994f636ef0e7847cd
