Parse and expose ownership transfer for instance parameters

Knowing the ownership transfer for instance parameters is
necessary for correct memory management of functions which
"eat" their instance argument, such as g_dbus_method_invocation_return_*.
Parse this information from the gir file and store in the
typelib, and then provide new API on GICallableInfo to
retrieve this.
