ZJIT: Avoid compiling and direct sends to forwardable ISEQs

These `...` ISEQs have a special calling convention in the interpreter
and our stubs and JIT calling convention don't deal well. Reject for now.
Debugged with help from `@tekknolagi` and `tool/zjit_bisect.rb`.

Merely avoiding direct sends is enough to pass the attached test, but also
avoid compiling ISEQs with `...` parameter to limit exposure for now.

`SendWithoutBlock`, which does dynamic dispatch using interpreter code,
seems to handle calling into forwardable ISEQs correctly, so they are
fine -- we can't predict where these dynamic sends land anyways.
