- plugin system similar to mjpResourceProvider, but instead of loading a resource it converts an existing mjResource into an mjSpec.
- The returned spec is then composed into the referencing spec.
- This enables different file types to generate arbitrary specs, and allows us to separate format parsing from compilation code.
Follow up CLs will move some of the logic in src/engine for PNG, USD, KTX, OBJ loading into decoders.
The mj_parse function MjSpec from a given file, it's a more generic version of mj_parseXML.
In it's implementation, mj_parse as opposed to mj_parseXML will look for any registered decoder and
not assume we are striclty dealing with MJCF.

`xfrc_applied` mostly contains user perturbations which are rare. It is very often identically zero and for large arrays `mju_isZeroByte` is significantly faster than `mju_isZero`.

This includes the filament, toolbox, and studio projects.
Adds a MUJOCO_BUILD_STUDIO option to enable building of the `studio` app (disabled by default).
Adds a MUJOCO_USE_FILAMENT to allow the studio app to use the filament rendering backend. A separate MUJOCO_USE_FILAMENT_VULKAN flag can be used to enable vulkan rendering.

This ensures that at e.g. the barycenter of the triangle each vertex has weight 1/3, as one would expect with barycentric coordinates, rather than 1/sqrt(3). This makes it consistent to the finite element interpolation used in the passive elastic forces.

The smaller size is a warning/error on some targets:
```
error: ‘ bytes’ directive output may be truncated writing 6 bytes into a region of size between 0 and 15

This function allows the caller to extract a subset of components of a state previously obtained via `mj_getState` without having to first write it back into `mjData`.

This is strictly an out array and should not be read before it is written to. This change improves MSAN coverage of engine code.

The truth is that all these solver-related values should be moved out of `mjContact` altogether, but that can be done in a future followup.

This is intended as a drop-in replacement for mjr_render to enable high
quality, physically-based rendering (PBR) using the filament render engine.
This is a work-in-progress and, as such, some features may be missing. This
is also a code-only drop; build files (including instructions on how to
generate the filament materials) will be provided at a later date.
This library is intended to be run with the experimental studio app.

Also, unify the meaning of fitting a geom to an AABB: it now means to find the smallest geom such that its AABB contains the mesh AABB.

Previously this was just used for the USDA file format token, which we can confidently just construct ourselves.
Since [this PR in OpenUSD](https://github.com/PixarAnimationStudios/OpenUSD/commit/5bb9ad1fb2a034e1f9b48c7db936f296b5b78e25) the file lives in a different place now and public usage will be deprecated anyways.
