[PATCH] mm: Remove unused page_is_file_lru() function

[Ye Liu <ye.liu@linux.dev>]

From: Ye Liu <liuye@kylinos.cn>

The page_is_file_lru() wrapper function is no longer used. The kernel
has moved to folio-based APIs, and all callers should use
folio_is_file_lru() instead.

Remove the obsolete page-based wrapper function.
