Port vfs1 implementation of sync_file_range to vfs2.
Currently, we always perform a full-file sync which could be extremely
expensive for some applications. Although vfs1 did not fully support
sync_file_range, there were some optimizations that allowed us skip some
unnecessary write-outs.
Updates #2923, #1897.
