Adding typed Parcel readMap and readHashMap APIs.

Added typed read API of `readMap` and `readHashMap`,
that takes extra clazz parameters check that the class written
on the wire is the same or a descendant from the one provided
as the key and value arguments.

Doing so could enhance the security of Parcel deserialization,
as it would prevent unexpected types of objects being deserialized.
More details can be found at go/safer-parcel.
