refactor(ngcc): pass dependency info to collectDependencies() (#34494)

Browse Source 
Rather than return a new object of dependency info from calls to
`collectDependencies()` we now pass in an object that will be updated
with the dependency info. This is in preparation of a change where
we will collect dependency information from more than one
`DependencyHost`.

Also to better fit with this approach the name is changed from
`findDependencies()` to `collectDependencies()`.
