fix "Maximum call stack size exceeded" on `resolveChildren`s `results.push.apply(results, result)`

Summary

Related to https://github.com/solidjs/solid/issues/2542

What happens is that the children helper crashes when trying to results.push.apply(results, [149k items]), as it overflows the max amount of arguments a function can have.

Line https://github.com/solidjs/solid/blob/0af2c2b4dc5f7da8022c16563c25d0687f68aff3/packages/solid/src/reactive/signal.ts#L1749

Now, if we want to fix this, I'm honestly not sure, considerations:

1. if a component can return data, say an array with 200k items, then we want to fix it.
2. for performance, I suppose (didn't measure), that checking for the length is negligible, (as in no performance impact)
3. this fix probably helps to get something dirty done fast, to then be edited to do it the right way, say use something like TanStack Table or TanStack Virtual

Think point 1 gets me. If a component that can return data ends somehow being resolved by the children helper, then I suppose we should fix this.

Question: should also apply the edit to ? 🤔 https://github.com/solidjs/solid/blob/0af2c2b4dc5f7da8022c16563c25d0687f68aff3/packages/solid/bench/libraries/s-mod.cjs#L293

How did you test this change?

Test passes, I also tested it by hacking the solution in vites output.
