kselftest: mm: integrate huge page checks

check_large_folios() only checks for large folios without distinguishing
between anonymous and file-backed huge pages.

To add huge page type checking, integrate the huge page checks into
__check_huge() and __check_type():

  1. If hpage_size == pmd_pagesize, check PAGE_IS_HUGE instead of using
     check_large_folios(), since only the mapping type matters. This
     identifies PMD-mapped huge pages.

  2. Otherwise, use check_large_folios() to detect large folios. This
     covers mTHP cases.

  3. Check the folio flags according to the huge page type via
     __check_type()
