Write aura::Window walker with fence hopping for accessibility for SingleProcessMash

Project Member Reported by jamescook@chromium.org, Dec 4 
It needs to go from a proxy aura::Window in ash to the client aura::Window in the browser code, and vice versa.

Ash, or some ash-specific part of the browser, will inject this into //ui/views/accessibility when SingleProcessMash is enabled.

There might be a complication around timing -- the proxy windows are not created immediately when the browser-side windows are created.

Fix double-parenting in AXWindowObjWrapper under mash

Under mus/mash both the WindowTreeHost's root aura::Window and the content
aura::Window will return the same Widget for GetWidgetForNativeView(). Only
return the Widget for the content window, not the root, since otherwise
we'll end up with two children in the AX node tree that have the same
parent.

This allows AXAuraWindowUtilsTest to run under views_mus_unittests and
unblocks some future tests.

chromeos: Support accessibility automation under SingleProcessMash

Introduce AXAshWindowUtils to allow the accessibility subsystem to
convert between ash proxy windows and browser client windows while
serializing the AX node tree.

Support out-of-process clients like shortcut_viewer by skipping the
proxy conversion, since they use the AXHost mojo service and depend
on having the ash-side windows and widgets serialized.

One side effect of this change is that the entire ash desktop is
serialized with the first AXTreeUpdate when ChromeVox is enabled.
This does not seem to cause any issues in practice.

Bug:  911776 
Test: added to ash_unittests
