Is your feature request related to a problem? Please describe (REQUIRED):
As far as I understand, the model component will always have limitations, because it has to support animations and other usefulness and standard GLTF stuff (for example). And only with mesh it will be possible to achieve real customization in rendering.

So it would be cool to add instancing for mesh, so that mesh would be on par with model.

Describe the solution you'd like (REQUIRED):
Instanced attributes for meshes, the same as models have.

Describe alternatives you've considered (REQUIRED):
I can use models, but I want to optimize vertex format to reduce GPU load.

Additional context (OPTIONAL):
Plus, it would be great to add indexed buffers for meshes:

• Add option for indexed vertices for buffers to be used with the mesh component. #5477
