[13.x] Restore iterable support to Arr::every() and Arr::some()

[Amirhf1]

Arr::every() and Arr::some() document support for iterable values, but currently pass them directly to array_all() and array_any(), which only accept arrays.
As a result, passing an ArrayIterator, generator, or other non-array iterable throws a TypeError.
This change retains the native PHP helpers for arrays while restoring the original short-circuiting iteration behavior for other iterables.
Regression tests also ensure callback values and keys are passed correctly.

Wouldn't it be enough to call Arr::from() on the input before passing it to array_all()?

Suggested change

	if (is_array($array)) {
	return array_all($array, $callback);
	}
	foreach ($array as $key => $value) {
	if (! $callback($value, $key)) {
	return false;
	}
	}
	return true;
	return array_all(self::from($array), $callback);
