Previously only the trackpad could be used to navigate this view.
Now we can zoom and pan around using our mouse wheel and scroll.
Additionally, this commit fixes many issues related to the visualization of the injector graph visualization, allowing it to be more compact without impacting legibility and minimizing edge collisions in larger graphs.

This commit introduces 2 new features into DevTools.
Directive level dependency inspection: Users can now view which dependencies their directives have injected in the property viewer tab. This view displays not only the dependency but also the resolution path that was used to service the injection.
Injector graph inspection: Users can now view a visualization of the element and environment hierarchies in their application. These trees are displayed separately but on the same page in the Injector Tree tab. User can click on individual injectors to view a list of all the providers configured in that injector, as well as highlight the resolution path from that injector to the root (with the corresponding environment injector connection highlighted as well).
