Introduce `struct erofs_iomap_iter_ctx` to hold both `struct page *`

`erofs_iomap_end()`.
With this change, fiemap and bmap no longer need to read inline data.
Additionally, the upcoming page cache sharing mechanism requires
passing the backing inode pointer to `erofs_iomap_{begin,end}()`, as
I/O accesses must apply to backing inodes rather than anon inodes.
