RT-19446 introduced support for native bundle generation. We need to showcase this in public samples.
Note that native bundles will only be produced if:
   a) 7u6 jdk is used to build sample
   b) required external tools are installed (WiX, Inno Setup 5 on windows)
Otherwise bundle generation step may be no-op.

Plan:
   - BrickBreaker to generate default bundles (customized only through ant settings)
   - SwingInterop to produce default bundles (demo cobundles for Swing applications)
   - Ensemble to produce customized bundles
