ProjectExplorer: Rework mode main window

The existing solution with the special-style horizontal
kit selector comes from a time when there was typically
one, at most four targets. Today's setup can easily
reach half a dozen targets with several toolchain versions
each and can't be sensibly handled with the overflowing
horizontal bar.

This here replaces the horizontal kit selector bar as
well as the top level project "tab bar" with a normal
tree view. All targets are visible (but possibly disabled)
at once, and can be enabled/disabled using the context
menu on the tree items.
