  Vulkan: Add framework for internal shaders.
  
  Vulkan intenal shaders are stored in a ShaderLibrary, and this is
  owned by the RendererVk. This way the shaders are reused between all
  the different Contexts. They are initialized lazily to keep init time
  low. They also have an associated Serial (called a ProgramSerial) so
  they can be identified in a PipelineDesc (used by the Pipeline cache).
  
  We use a python script to build and invoke the glslang validator, that
  also produces SPIR-V binary code snippets. These snippets are gathered
  into an auto-generated file that is exposed via an auto-generated
  header file. The InternalShaderID enum class gives access to the
  internal shaders that are shared through the Vulkan back-end.
  
  This also adds simple clear shaders to be used in masked color clears.
  The patch doesn't add any functionality but it is split off from the
  color clear functionality to keep the code size down.
