Tracker for performance improvements to CrOS files app, gallery, video_player, audio_player . Particularly around load times.

Some observations
 - code isn't minified / closure-compiled in release
 - A lot of code is loaded in both the background page and for each foreground/window page, even though they share a JS context
   * although this needs to be balanced by every CrOS update running the background page for every component app at startup.. (maybe)
 - a lot of test code is baked-in
 - opening a second window in, e.g., the file manager should be almost instantaneous, but it's not: stuff loads again.
