Set private reference for classic script

Web developers can use `Dynamic Import` in a classic script; thus, we
need to save the script's private reference so that we can reuse it when
we're going to fetch a dynamic import module for a classic script.

Besides, because it's possible to use different executing context for a
dynamic import module (like `dynamic-import/string-compilation-other-document.html` WPT test),
we can't initialize a module owner at the timing of `SetScriptPrivate`;
thus, if the private module script doesn't hold an owner, we'll use a
DynamicImport owner for it.
