Fixes wrong sizes being displayed in usdview.
Also introduce a new test to ensure we catch as many of those kinds of errors as possible in the future.

Still missing compiler settings but will follow up in a future CL. Tried to add full coverage for testing setting of attributes to non-default values.

This adds an option MUJOCO_BUILD_USD_PLUGINS to the top level CMakeLists which allows us to build the usdMjcf file format plugin with the rest of mujoco.
In this first version, we allow building against either standalone USD or against Houdini (DCC) since it has it's own fork of USD. When building against standalone USD we also build the file format tests.

Because we introduce an additional parent scope when referencing a `Mesh` prim (required for instancing), we need to create an `over` prim that allows to actually operate on the to-be-referenced Mesh.

Adds primvar:displayColor/primvar:displayOpacity to the geom prim if its rgba attribute differs from the default (0.5, 0.5, 0.5, 1.0). This sets the color and opacity directly on the prim with no need for an external material, making it consistent with how rgba is used in mujoco.

We will still need to tag these with a custom API schema to ease round-tripping but that will follow creation of such a schema.
