[ADD] hw_screen: implement support for customer facing displays (#15303)

This adds the hw_screen module which is responsible for receiving
rendered HTML from a POS client and sending it to a running Chromium
browser. This is done by sending Remote Debugging Protocol messages over
a WebSocket provided by Chromium. This allows hw_screen to evaluate
arbitrary JS. This is used to seamlessly (without flickering) update the
browser.

This also includes changes to the POSBox. X, Chromium and some
miscellaneous other programs were added. Functionality was added that
automatically displays a fullscreen, UI-less Chromium browser when the
POSBox starts up. This is accomplished through x_application.sh, which
gets executed only when a display is detected. After the browser starts,
it will display a specific screen until it receives the first order update
from a POS client.
Creates a public controller to be able to display the interface on an external
device not connected to the posbox (e.g. tablet)
