fw_iso_resource_once: add derived object to initiate allocation/deallocation by one shot

Current implementataion of Hinoko.FwIsoResource object includes functions
one-shot allocation/deallocation as well as basic functions for derived
objects. It's inconvenient in the derived object side.

This commit adds Hinoko.FwIsoResourceOnce object for future use to move
the one-shot functions.
