WebGPURenderer: Ignore diagnostic() method in Deno.

[Mutefish0]

I've ported a game to Deno using Three.js. However, diagnostic filters aren’t supported in wgpu, which Deno's WebGPU is based on.

Tracking issue:
gfx-rs/wgpu#5320

Heads up: Once gfx-rs/wgpu#6148 lands, and it's consumed in Deno, you should be able to revert this.

CC @crowlKats, who maintains Deno's WebGPU implementation. I'm not sure if or how Deno is tracking this functionality.

nope, we are not tracking this functionality, but i'll be keeping an eye on it now and make sure we update deno once its available
