Support actdim attribute on plugin actuators.
Remove the actuator_actdim callback. This callback leads to crashes when loading keyframes for models that have a stateful plugin.

Increased tolerance above zero in nutbolt.xml since now the two parts lock otherwise. Measured speedup of 2x in this example.
This solves the issue of scale-dependent step sizes. Tested on gears with 10cm diameter and 2cm thickness.

Change physical properties of `floppy_flex.xml` to resemble `floppy.xml`.
Make `Membrane` backward compatible with `Composite`.

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.

- Memory heuristic rounds up to the nearest MB.
- `simulate` reports total memory currently allocated in the info box.
- All example models use `<size memory/>` rather than legacy attributes.
- Regenerated `example_saved.xml` and reformatted original model in [overview chapter](https://mujoco.readthedocs.io/en/latest/overview.html?#examples).
- `<size>` top-level section does not get written if empty.

- Added new `cable` composite type:
* The `initial` parameter specifies the joint at the starting boundary: `free`, `ball`, or `none`.
* The boundary bodies are exposed with the names:`B_left` and `B_right`.
* The vertex initial positions can be specified directly in the XML with the parameter `vertex`.
* The orientation of the body frame **is** the orientation of the material frame of the curve.
- Added new `cable` passive force plugin:
* Twist and bending stiffness can be set separately with the parameters `twist` and `bend`.
* The stress-free configuration can be set to be the initial one or flat with the flag `flat`.
* New cable example showing the formation of plectoneme.
* New coil example.
* New belt example showing interaction between twist and anisotropy.
* Added test using cantilever exact solution.
