bluetooth: Add notification system to internals page.

Adds notification system to internals page using a snackbar UI element.

The snackbar system can be invoked from any page using Snackbar.show and
Snackbar.dismiss and come in a variety of styles (info, success, warning, and
danger) depending on the need of the caller. Multiple snackbar requests can be
queued and are shown one at a time.

Removes connection error column from DeviceTable.

Error and success messages are now shown in a snackbar displayed from
bluetooth_internals.js.
