Alessio Quaglino f25fc63f0f Default flex internal contacts to "false".
This function is unusual in the context of soft body simulations and has been a common gotcha for users, see e.g. #2500, #2079, #1900, and #1433. It should be used only if element inversion cannot be prevented otherwise.

Alessio Quaglino 7cdf180641 Introduce trilinear flex parametrization.
These flexes use only 24 DOFs (3 per vertex of the bounding box), while colliding with the full high resolution mesh.

On an 8x8x8 cube, the performance using DOFs at all vertices is

```
 Simulation time      : 18.74 s
 Steps per second     : 533
 Realtime factor      : 0.53 x
 Time per step        : 1874.4 µs

 Contacts per step    : 114.88
 Constraints per step : 3322.51
 Degrees of freedom   : 1536
```

With the new implementation, it is the following:

```
 Simulation time      : 1.82 s
 Steps per second     : 5507
 Realtime factor      : 5.51 x
 Time per step        : 181.6 µs

 Contacts per step    : 38.84
 Constraints per step : 155.36
 Degrees of freedom   : 24
```

Alessio Quaglino bfa78614c8 Require prefix for the attach tag.
For `mjs_attachFrame` and `mjs_attachBody`, require either a prefix or suffix.

It is tempting for users to not use a prefix (see #2162), but this causes issues. For example, it creates a duplicate "main" default class in the parent as a child of the already existing "main" default.
