libbinder_ndk: finalizeTransaction->AParcel_delete

AIBinder_finalizeTransaction has been removed and replaced with
AParcel_delete. This makes error handling easier and makes it possible
to clean up the in parcel without executing a transaction.

This comes with the loss of the check that the parcel is read in its
entirety as this check may be moved into libbinder or into an API above
this in order to simplify error handling.
