Provide explicit argument for asset cache ID.

This will allow assets to cache compiled results with different parameters. For example, we could cache both an RGB version of a texture and a Mono version.

Refactor: Convert mjCOctree::MakeOctree from recursive to iterative.
...
The octree construction is now performed using a breadth-first search with a `std::deque` to manage tasks. A new `OctreeTask` struct encapsulates the state for each node to be processed, and a helper function `Subdivide` is introduced for subdividing the Octree nodes.
Also reduce the number of (center, size) to (min, max) conversion for the bounding box representation in order to avoid duplicated vertices in the Octree due to floating point errors.

Resize keyframes also at the start of compilation.

Previously, it was assumed that attaching was the last operation performed on the mjSpec, so keyframes resulted in the incorrect size. In order to prevent information loss, we now only allow the resize function to expand the keyframe array, since attach should never remove a degree of freedom.
