This brings the master branch up to date with everything we've done
in the 8.8 branch. Adjusts for the new ILaunchTarget and targeted
launch delegate.
Also has a start at making more things common in the new build system.
With three extenders of it now in CDT, i.e. Qt, CMake, and Arduino,
it's obvious we can make things more common and make new extenders
less work.
Also undoes some of the work I've done to get Arduino onto the new
build system. Will need to redo it as we do the new common stuff.

Moved new build system to it's own plug-ins. Cleaned up the root
build configuration and toolchain classes and use them for Qt local
run builds. Also hooks Qt local run launch delegate to launch target
manager and associated delegate interface.

Includes adaptation of the Arduino build model where many of these
ideas started to the new model. And start of the Qt build system which
uses it.
