Looks like no code instantiated these via those odd service names (except for
ProgressMonitor/StatusIndicator instantiating ProgressBar via odd
"com.sun.star.awt.XProgressBar" service name until that got cleaned up in the
previous commit).
Also looks like no code instantiates them via their implementation names either
(in which case ProgressBar/ProgressMonitor/StatusIndicator would be dead code),
but maybe there is code that dynamically constructs those implemenation names
and calls creeateInstance on them? So best leave the implementations in for
now...
