faces/horizontalbars: Allow specifying the data range from config

In some cases, we may want to display sensors using this face that don't
have a proper min/max range. So add the same sort of configuration that
we have for other faces so it becomes possible to override the automatic
data range with a manually specified one.

While at it, port the actual bar implementation from a manual
implementation to a ProgressBar with overridden contentItem, as that
makes the code a fair bit easier to work with.
