Shared Storage: Align createWorklet's default data origin w/addModule's
We align the default data origin for createWorklet with that of
addModule to be the invoking context's origin. We also hook up the
dataOrigin option in createWorklet's options dictionary, so that
the script origin can be manually specified to be used as the data
origin instead.
