btrfs: introduce helpers for subpage uptodate status
Introduce the following functions to handle subpage uptodate status:
- btrfs_subpage_set_uptodate()
- btrfs_subpage_clear_uptodate()
- btrfs_subpage_test_uptodate()
These helpers can only be called when the page has subpage attached
and the range is ensured to be inside the page.
- btrfs_page_set_uptodate()
- btrfs_page_clear_uptodate()
- btrfs_page_test_uptodate()
These helpers can handle both regular sector size and subpage.
Although caller should still ensure that the range is inside the page.
