perf: Make next-page-static-info use Atom instead of String

[kdy1]

What?

Use swc_atoms::Atom instead of String in next-swc.

Why?

Atom does not allocate if another instance has the same value, meaning that clone() is a single atomic operation. But String allocates regardless of any other occurrence.

Closes PACK-3860
