Linus Groh f27bc56e5e LibJS: Capture promise capability in new_promise_capability() executor ...

This is how the spec suggests implementing this; we need to be slightly
more verbose as our PromiseCapability implementation cannot hold
arbitrary JS values.

Unfortunately it makes the error message slightly more ambiguous as we
no longer expose the non-function value to the outer scope (we could!),
but at least we don't UAF the stack allocated values anymore :^)
