perf(turbopack): Optimize `next_page_static_info` (#79009)
### What?
Avoid using `FxHashMap` for the `next_page_static_info` pass and use a custom trait instead. The goal of using a custom trait is to keep it general and make the responsibility of each code.
### Why?
We do not need to allocate at all.
Also, visitor calls are expensive, and we don't have to pay for them in this case.
### How?
- Closes SWC-655
