Rename page_copy_prealloc() to folio_prealloc(), which is used by
more functions, also do more folio conversion in page fault.

v3:
- drop patch6 as Small-sized THP for anon will change anon allocation
- correct do_cow_page to do_cow_fault in subject and changlog
- add RB of Vishal

v2:
- add folio_test_large check in ksm_might_need_to_copy() and
  replace page->index to folio->index, per David, Matthew
- add RB of Sidhartha
