1) Both ext4 and xfs have supported FS_XFLAG_DAX so move it to generic.
2) Modifying FS_XFLAG_DAX on flies does not take effect immediately so
make files inherit the DAX state of parent directory.
3) Setting/clearing FS_XFLAG_DAX have no chance to change S_DAX flag if
mount with dax option so remove the related subtest.
4) Setting/clearing FS_XFLAG_DAX doesn't change S_DAX flag on older xfs
due to commit 742d84290739 ("xfs: disable per-inode DAX flag") so
only do test when fs supports new dax=inode option.
