Adding method to check if a Parcel has any Binders marshalled in it.

This is an extension to the existing `hasFileDescriptors` method, both of which are "Active Objects" of a sort and allow writes across processes.
This check would be useful to perform validations on Bundle entries or
any Parcelable type if it only contains non-active objects and can be
essentially treated read only without having to inspect the marshalled
parcel object.
