fix: make all tests green with new view engine and JIT

Note that this does not yet include enabling the view engine
by default.

Included refactoring:
- view engine: split namespace of elements / attributes already
  when creating the `NodeDef`
- view engine: when injecting the old `Renderer`, use an implementation
  that is based on `RendererV2`
- view engine: store view queries in the component view, not
  on the host element
