Expand description

Generate vtable static + TPIE macro invocation for an empty trait impl.

When #[miniextendr] impl Trait for Type {} has no method bodies, this generates the vtable static and delegates to the __mx_impl_{Trait}! macro (generated at the trait definition site) to expand C/R wrappers.

Requires a fully qualified trait path (at least 2 segments) so the TPIE macro can be resolved from the trait’s crate root.
