Skip flex edge Jacobian if not needed.
...
When equality constraints and built-in passive forces are not present, edge Jacobians are unused. This gives a 3x speedup in `mj_kinematics` in `floppy_flex` (from 0.2ms/step to 0.06ms/step).
Changed the default options of `floppy_flex` to match those of `floppy` for a fair comparison.
