Fix accessor depth calculation for SmartSyntaxInterpreterPlugins.  The scheme
still doesn't follow at: chains thropugh derived pointers starting with
firstIndexableField: but it's good enough, and a big step up from assuming
the accessor depths of primitives in all such plugins is 0.

Implement what I think Ken wants for ThreadedRiscV64FFIPlugin>>ffiCalloutTo:SpecOnStack:in:,
i.e. to treat float & double differently from the array of float/double.
