docs(*) fix dangling links in API docs (#16632)

* docs(animations): fix links to `Component` animations

* docs(core): fix links to `ReflectiveInjector` methods

The `resolve` and other methods were moved from the
`Injector` to the `ReflectiveInjector`.

* docs(core): fix links to `Renderer`

The local links were assuming that that methods were on the
current document (e.g. `RootRenderer`), but they are actually
on the `Renderer` class.

* docs(router): fix links to methods

* docs(forms): fix links to methods

* docs(core): fix links to methods

* docs(router): fix API page links and an internal link
