Add full buffered I/O support using the iomap framework to the exfat
filesystem. This will replaces the old exfat_get_block(),
exfat_write_begin(), exfat_write_end(), and exfat_block_truncate_page()
with their iomap equivalents. Buffered writes now use
iomap_file_buffered_write(), read uses iomap_bio_read_folio() and
iomap_bio_readahead(), and writeback is handled through iomap_writepages().
