explore other useful migration schematics to help with /zoneless adoption

[markgoho]

the imports migration looks good, but we might be able to help folks out with other API migrations -- I'm manually migrating a bunch of specs right now, I'll see if anything pops out as an obvious win

[markgoho]

a few that came up that might be worth investigating:

• Rewrite simple inputs / componentInputs cases to bindings with inputBinding(...).
• Rewrite output handler wiring (on-style cases) to Angular outputBinding(...).
• Migrate component-scoped provider overrides to configureTestBed(...) + TestBed.overrideComponent(...).
• Detect router-dependent components and add/suggest provideRouter([]) when moving to /zoneless.
• Rewrite obvious ATL navigation-helper usage to the recommended zoneless routing pattern (or leave a targeted TODO).

@markgoho I think it's a good suggestion.
If you want you can create a PR for one of these changes.

sure! I just need to familiarize myself with the migration system/syntax, and I can probably knock a few of these out
