The Metal 4 and CAMetalLayer vocabulary needed by the first frame.

The two small structures cross as typed foreign storage through either the default NSInvocation bridge or direct libffi calls in an explicitly unchecked scope. They stay declarations in the same message system as scalar and object calls; no per-selector shim is needed.
