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.

This extends both the spec and the XML definition to allow specification of a material name on a mesh. This material acts as a fallback in the case that the referencing geom element does not specify a material of it's own.

Modify user values in mujoco to allow users to provide cleanup functions to avoid memory leaks.

For the MJCF -> USD plugin, and I suspect other usecases for user values, it's necessary to give ownership of the object to Mujoco. However since they get type erased, we can't clean up the data automatically for the user. Instead this allows c++ clients to provide a cleanup function with their data.

Store the mjsCompiler -> appended mjSpec map when appending an mjSpec.
...
Previously, we stored the source `mjSpec` during a copy as a hack for having access to the compiler options, but this is not robust since we cannot guarantee that 1) the source `mjSpec` is not destroyed before we need to look up the compiler options nor 2) that the `mjSpec` was appended without a copy.
While 2) could be solved by simply handling an additional case in `mjCModel::FindSpec`, using a map also solves 1) and it is easier to understand.
