  Vulkan: Call glslang at compile time
  
  With this change, the ANGLE translator immediately compiles the
  generated GLSL into SPIR-V with glslang and discards the source.  This
  is in preparation for generating SPIR-V directly, by making the frontend
  and backend already able to digest it.
  
  This change also allows the expensive glslang calls to be parallelized,
  improving the following perf test by about 20%:
  
      LinkProgramBenchmark.Run/vulkan_compile_and_link_multi_thread
  
  Previously, the test was run as such in the Vulkan backend:
  
      Main           Thread 1          Thread 2
      Compile1 --->
      Compile2 --------------------->
                    Translator        Translator
               <---
               <---------------------
      Link
  
      glslang
       for
        shader1
  
      glslang
       for
        shader2
  
      Done
  
  With this change, it is run as such:
  
      Main           Thread 1          Thread 2
      Compile1 --->
      Compile2 --------------------->
                    Translator        Translator
                     glslang           glslang
               <---
               <---------------------
      Link
      Done
  
  glslang_wrapper_utils no longer interacts with glslang! A rename will
  follow.
