Can we kill this entire file? Seems like the rest might be able to move into
web_app_win.

Yeah I agree. Could we do that in another CL? The windows-specific part seems
largly unrelated to the UpdateShortcutInfoAndIconForApp part. Also it's not
blocking anything.

 // UpdateShortcutWorker holds all context data needed for update shortcut.
 // It schedules a pre-update check to find all shortcuts that needs to be
 // updated. If there are such shortcuts, it schedules icon download and
 // update them when icons are downloaded. It observes TAB_CLOSING notification
 // and cancels all the work when the underlying tab is closing.
