fix(overlay): injection errors for scroll strategy providers in lazy-loaded modules (#11213)

Fixes injection errors being thrown by the overlay-based providers that have injection tokens for the default scroll strategy. The error comes from the fact that the scroll strategies were being provided at the root, whereas the `Overlay` provider was provided normally, causing it to be missing when a module is lazy-loaded.

Fixes #10820.
