Deprecate unsafe parcel APIs

Deprecate unsafe parcel APIs and point to the safer ones that take the
expected type as parameter. Where applicable also mention the typed ones
that take the creator as argument since those are also more performant.

APIs deprecated here are:
* readMap(Map, ClassLoader)
* readList(List, ClassLoader)
* readHashMap(ClassLoader)
* readArrayList(ClassLoader)
* readArray(ClassLoader)
* readSparseArray(ClassLoader)
* readParcelable(ClassLoader)
* readParcelableCreator(ClassLoader)
* readSerializable()
