feat(devtools): clean up router tree for stable release
Addresses some cleanup items for the router tree: - No longer loads router ng global APIs as a side effect of importing the router. Rather this is now a runtime step that occurs when provideRouter is called. - No longer depends on router.navigateByUrl in Angular DevTools. There is now a dedicated global util for this - Router instance logic no longer depends on token name - Prevents navigating to lazy or redirect routes (these don't have an associated component)
