Consolidate all Vertex and Index buffer creation inside the
Mesh class. Users now set data pointers in the MeshData
from which the Mesh class will create the filament buffers.

A future change will update all callers to use this
method for creating Meshes after which we will remove
the constructor that takes explicit filament objects.

Update the Mesh class so that it manages the lifetime of the
vertex and index buffers.

TextureConfig describes the properties of the texture (e.g.
width, height, pixel format, etc.). TextureData contains
the binary payload of the texture.

All objects that are specific to the mjModel (meshes, textures, etc.)
are now managed by a ModelObjects class which is owned by the SceneView
and not the FilamentContext.

Separate out the parts of the FilamentContext initialization that
depends on the mjModel into a separate Init function.

Setting values in the mjrContext is only useful for the classic
renderer.

Add a warning in user_model.cc if a flex is not rigid and has no edge equality constraints or passive forces (edge stiffness, edge damping, or vertex damping). Such flexes would not affect the simulation. A test case is added to verify the warning.

Reflective surfaces (planes) use a custom shader to blend their
texture with a texture that contains the reflected image. The
reflected image is rendered to a texture as a separate render
pass in the SceneView.
Because reflective textures are generated after the preparation
phase, additional functions are needed to reapply the texture
to the drawable.

A future CL will implement reflective surfaces and make use of these materials.

Add a new mjpEncoder plugin type mirroring the existing mjpDecoder pattern.
Encoders serialize an mjSpec + mjModel to an mjResource for a given format.
New API functions:
- mjp_registerEncoder: globally register an encoder
- mjp_defaultEncoder: zero-initialize an encoder struct
- mjp_findEncoder: look up an encoder by filename extension or content type
The mjfEncode callback takes (mjSpec*, mjModel*, mjVFS*, mjResource*) and
returns 0 on success. Writing to mjResource keeps symmetry with the decoder
reading from mjResource and leaves the door open for writable resource providers.

The computation of tactile sensor values for each taxel is now parallelized using the MuJoCo threadpool when the number of taxels exceeds a threshold. Each thread processes a batch of taxels, accumulating forces from all colliding geoms.

The `vertcollide` attribute in flex and flexcomp contact specifications has been removed since the next mjWarp release will support flex collisions. This attribute was previously used to enable vertex-based collisions by adding sphere geoms at flex vertices. The functionality associated with this attribute has been deprecated and removed from the XML parser, documentation, and internal data structures. Affected example XML files have also been updated.

model_holder.cc modified to disable multi-threaded compilation for WASM builds. index.html `animate()` function modified so the animation rendering loop executes asynchronously with async/await calls. These changes are sufficient to make xml files without references work (e.g., humanoid.xml), more work is needed to make the vfs work so multi-file models can load.

When freeing a stack frame, only poison the newly-freed memory region
`[old_top, new_top)` instead of the entire region `[limit, top)`. The old
code redundantly re-poisoned already-poisoned memory on every
`mj_freeStack` call.
Benchmarking `engine_forward_test` under ASAN:
- Before: 99.3s
- After: 75.6s (~24% faster)
