  WGSL: move DeclareDefaultUniforms() out of SPIR-V
  
  WGSL needs the same thing (default uniforms gathered into
  an interface block).
  
  Changes 3 things in the file move:
  1. Now capable of adding a named interface block (Vulkan's
     is nameless) to hold the default uniforms.
  2. Removes inactive uniforms
  3. Deals with the case where there are no active default
     uniforms, by not declaring an interface block at all.
