Kairui Song 7d0f0f0615 mm: move folio_index to mm/swap.h and remove no longer needed helper ...

There are no remaining users of folio_index() outside the mm subsystem. 
Move it to mm/swap.h to co-locate it with swap_cache_index(), eliminating
a forward declaration, and a function call overhead.

Also remove the helper that was used to fix circular header dependency
issue.
