Keep tree lists updated at all times.
...
This simplifies the compiler logic since an updated tree list was necessary at many stages (e.g. attach and keyframes resizing) and it will be anyway required when computing the mjSpec signature.

Remove MuJoCo stack calls in nativeccd.
...
1. There is now thread local static memory for use with a conservative max number of iterations needed for contact.
2. For possible needs of high precision contact recovery with large iteration numbers (i.e. ellipsoid-ellipsoid collisions), there are callbacks to allocate memory when needed.
