Online folios are locked file-backed folios which will eventually
keep decoded (e.g. decompressed) data of each inode for end users to
utilize. It may belong to a few pclusters and contain other data (e.g.
compressed data for inplace I/Os) temporarily in a time-sharing manner
to reduce memory foot
Use bio_for_each_folio() to iterate over each folio in the bio and
there is no large folios for now.

It is a straight-forward conversion. Besides, it's renamed as
z_erofs_scan_folio().

Introduce a folio member to `struct z_erofs_bvec` and convert most
of z_erofs_fill_bio_vec() to folios, which is still straight-forward.

`justfound` is introduced to identify cached folios that are just added
to compressed bvecs so that more checks can be applied in the I/O
submission path.
EROFS is quite now stable compared to the codebase at that stage.
`justfound` becomes a burden for upcoming features. Drop it.

Convert erofs_try_to_free_all_cached_pages() and
z_erofs_cache_release_folio().
Besides, erofs_page_is_managed() is moved to zdata.c and renamed
as erofs_folio_is_managed().

There are mainly two reasons that thp_get_unmapped_area() should be
used for EROFS as other filesystems:
- It's needed to enable PMD mappings as a FSDAX filesystem, see
commit 74d2fad1334d ("thp, dax: add thp_get_unmapped_area for pmd
mappings");
- It's useful together with CONFIG_READ_ON
