Add missing SVGs

This commit adds missing SVGs for all wizban icons in Eclipse Platform. Furthermore SVGs for icons in the bundles `org.eclipse.unittest.ui`, `org.eclipse.tips.ui` and `org.eclipse.tips.ide` are added by copying from other bundles or creating from scratch. The examples in .exsd files are adjusted.
