v0.1.0: start of workflow for the WebGPU team

This release targets the WebGPU team, and may not offer much context for those outside of it. Sorry, not sorry! You have been warned!

This release renames the current whippit binary to moz-webgpu-cts, and adds the fmt and triage commands. Now that --gecko-checkout is inferred from the CWD if not specified, it should now be able to cargo install this binary and run moz-webgpu-cts $subcmd without any further configuration!
