Refactor sparse Cholesky factorization into symbolic and numeric phases.
...
The new symbolic function is a generalization of the function it replaces. In this CL it takes two unused temp arrays. The actual change in behavior happens in the followup.
New benchmark test output below ("L" is 2 humanoids and 100 free objects, "XL" is 100 humanoids). Note that `symbolic` is only ever called once per Newton iteration, while `numeric` is sometimes called multiple times (when the rank-1 update fails), hence timing them separately is valuable.

This change makes `mjtSize` a signed, rather than unsigned 64-bit integer. While sizes are non-negative, the type promotion rules for unsigned integers can lead to unituitive downstream bugs, and 8 billion terabytes are enough bytes.

Fast flex: Interpolate contact points directly.
...
For each contact point, we used to first compute the vertex weights on a triangle and then add a contact point per vertex using the flex interpolation (trilinear or quadratic), obtaining the total weight by multiplying the vertex weight and the basis function value at that vertex. After this change, each contact point is added directly by evaluating the basis function directly a the point.
