Add mju_mat2Rot.
...
This function extracts the 3D rotation from an arbitrary 3x3 matrix by refining the input quaternion. It is based on the paper "A robust method to extract the rotational part of deformations" by Müller, Matthias, Jan Bender, Nuttapong Chentanez, and Miles Macklin.

Replace double- or single-precision-denominated function calls in the engine with the equivalent mjtNum-denominated calls. This avoids unnecessary casting or precision loss when MuJoCo is compiled for 32-bit float precision. Accordingly, remove #include <math.h> from all engine source files.

Deprecate mju_rotVecMat and mju_rotVecMatT in favor of mju_mulMatVec3 and mju_mulMatTVec3.

Improve mju_cross implementation.
...
- Allow in-place cross product a = a x b using `mju_cross(a, a, b)`.
- Easier for compiler to optimize since tmp cannot alias a or b (verified with godbolt).
