src: fix warnings around node_options

* header explicit usage, order, and reduce use of `*-inl.h` * pointer -> const reference when possible * no variable recyclicng * `std::begin/end` prefered over `instance.begin/end` * `USE` for explicit unused resaults PR-URL: nodejs#26280 Fixes: nodejs#25593 Reviewed-By: Joyee Cheung <joyeec9h3@gmail.com>
