fix(views): remove dynamic component views, free host views, free embedded views

Closes #2472
Closes #2339

BREAKING CHANGE
- `Compiler.compile` has been removed, the only way to compile
  components dynamically is via `Compiler.compileInHost`
- `DynamicComponentLoader.loadIntoExistingLocation` has changed:
  * renamed into `loadIntoLocation`
  * will always create the host element as well
  * requires an element with a variable inside of the host component view
    next to which it will load new component.
- `DynamicComponentLoader.loadNextToExistingLocation` was renamed into
  `DynamicComponentLoader.loadNextToLocation`
- `DynamicComponentLoader.loadIntoNewLocation` is removed
  * use `DynamicComponentLoader.loadNextToLocation` instead
    and then move the view nodes
    manually around via `DomRenderer.getRootNodes()`
- `AppViewManager.{create,destroy}Free{Host,Embedded}View` was removed
  * use `AppViewManager.createViewInContainer` and then move the view nodes
    manually around via `DomRenderer.getRootNodes()`
- `Renderer.detachFreeView` was removed. Use `DomRenderer.getRootNodes()`
  to get the root nodes of a view and detach them manually.
