ash: A first step for the uber tray.

As a first step, there are items to open settings, help pages, and an item to
allow [un]muting volume.

The resources have not been uploaded yet. That will be done in a separate CL to
allow this one to go through trybots etc.

This new uber-tray can be turned on at runtime using --ash-uber-tray flag.

BUG=110130
TEST=none yet. will be added when a little more fleshed out.
