An engine instance needs to share the following with its parent:

* `service:-glimmer-environment` (only for glimmer)
* `renderer:-dom` or `renderer:-inert`, depending on whether the environment
  is interactive

Ensure that Cache lookups are performed using the correct owner.

Ensure that engines are destroyed _before_ top-level views so that top-level
views are not re-instantiated during engine teardown.

Ensure that the owner being used is not the environments default
`Owner`, but it is the owner that the template is being looked up by.

For late bound templates this means the components owner, and for normal
templates (looked up from registry) it is passed to the factories
`.create` method by the container itself.
