This CL removes status_area_widget_test_api.test-mojom and related mojo
code since ash lives in the browser process, not a separate process and
it is the remains of previous efforts to run ash in a separate process.

It moves TapSelectToSpeakTray from StatusAreaWidgetTestApi to
SystemTrayTestApi and removes StatusAreaWidgetTestApi.
