Only keep Parcelables if used

Use `-keepclassmembers` instead of `-keep` for Parcelable types
and their CREATOR members. This allows shrinking of Parcelable types
that aren't referenced while still preserving the necessary CREATOR
member when the classes are kept. This saves ~3MB across various
platform targets.
