refactor(view_compiler): codegen DI and Queries

BREAKING CHANGE:
- Renderer:
  * renderComponent method is removed form `Renderer`, only present on `RootRenderer`
  * Renderer.setDebugInfo is removed. Renderer.createElement / createText / createTemplateAnchor
    now take the DebugInfo directly.
- Query semantics:
  * Queries don't work with dynamically loaded components.
  * e.g. for router-outlet: loaded components can't be queries via @ViewQuery,
    but router-outlet emits an event `activate` now that emits the activated component
- Exception classes and the context inside changed (renamed fields)
- DebugElement.attributes is an Object and not a Map in JS any more
- ChangeDetectorGenConfig was renamed into CompilerConfig
- AppViewManager.createEmbeddedViewInContainer / AppViewManager.createHostViewInContainer
  are removed, use the methods in ViewContainerRef instead
- Change detection order changed:
  * 1. dirty check component inputs
  * 2. dirty check content children
  * 3. update render nodes
