Global item does not support 'const'

[haoyunfeix]

Shader:

      const workGroupSizeX = 256u;
      const workGroupSizeY = 1u;
      const workGroupSizeZ = 1u;

The compiler doesn't like it:
$ naga simple.wgsl

error: expected global item ('struct', 'let', 'var', 'type', ';', 'fn') or the end of the file, found 'const'
  鈹屸攢 simple.wgsl:1:7
  鈹?[0m

Naga currently uses let for global constants.
It will be fixed in #2065.

Hey @SparkyPotato, thanks for the reply. Looking forward for the resolution of #2075!

I really hope deno supports TensorFlow.js with WebGPU backend, please do let me know if there is anything I can do to help pushing forward.

I'm a bit busy right now, but hope to get it done soon.

@SparkyPotato no worries, take your time!
