  WGSL: default uniforms gathered in interface block
  
  The default uniform struct was being manually output by
  OutputUniformBlocksAndSamplers(), which did not add the appropriate
  @align(16) annotations to lay the struct out according to WGSL's
  uniform address space layout requirements.
  
  This CL uses Vulkan's method of gathering the default uniforms
  into an interface block. The interface block will be output
  normally by the traverser, including @align() annotations.
  The variable declaring an instance of the interface block is
  still output by OutputUniformBlocksAndSamplers() because it needs
  special @group() and @binding() annotations.
