fix(material/tooltip): regression when injecting ViewContainerRef (#30500)

#30440 deferred the injection of some dependencies in the tooltip, including `ViewContainerRef`. This is problematic, because the act of injecting `ViewContainerRef` changes the shape of some internal data structures in the framework's runtime. As a result, hovering over a tooltip that has been hydrated will throw a runtime error because the structure from the server no longer matches the structure on the client.

Fixes #30498.
