Bug 515926 - [tests] Prepare infrastructure for debug view test

- added extra debug perspective to show debug view in full size on the
left side from the editor. This allows debug view to materialize all
visible stack elements.
- added extra AbstractDebugUiTests as a base class for UI related debug
- extended TestUtil.waitForJobs() to allow ignoring some job families.
