  [WebGPU] It is legal to draw zero instances, vertices, or indices in WebGPU but this results in a validation error

Reviewed by Tadeu Zagallo.

The validation error rightfully errors if we attempt to draw zero instances,
vertices, or indices, but this is legal to perform in WebGPU without an error,
so simply return.
