The code in GLTF exporter is probably suboptimal - it's not clear that
we need to clone the attribute if it's already relative.

On further reflection it shouldn't be necessary - it's probably better
to maintain "exact" match between the shader code and CPU-side code that
may use (pos - morph) * w directly.

This uses the newly added functionality for loading morph target data in
GLTF loader; there's no need to clone attribute data anymore.

The shader code is now a bit simpler and relies on the precomputed base
influence value; JS code sets it up appropriately.

This adds the attribute and the necessary plumbing for various JS
functions; there's no support for specifying this for the shader to
consume yet.
