  WebGPU: Compute passes
https://bugs.webkit.org/show_bug.cgi?id=250863

Reviewed by Myles C. Maxfield.

Implement compute passes which are needed to start
passing a lot of the CTS tests which create a simple
compute shader and read back the result, to ensure
the adapter was created.

https://bugs.webkit.org/show_bug.cgi?id=251171 has
been filed for tracking getting the threads per thread
group size from the shader compiler.
