Move collection-ktx extensions into main artifact

It's no longer necessary to keep kotlin extensions in a separate
artifact since we pull in Kotlin stdlib into the main artifact. To
improve visibility, but keep compatibility with existing -ktx users, we
can keep publishing an empty -ktx artifact, but move all the extensions
into the main artifact.

Relnote: "Migrate colection-ktx extensions into the main artifact,
  androidx.collection:collection. This change makes the pre-existing
  -ktx extensions accessible to Kotlin users without requiring the -ktx
  dependency, while still maintaining compatibility for existing users.
  Maintaining these extensions in a separate -ktx artifact is no longer
  beneficial since the main artifact has moved to Kotlin."

Test: cd collection && ./gradlew bOS
