  Re-land "Vulkan: Roll loader/validation layers SDK. (2/2)"
  
  Second re-land fixes git.bat access on developer machines.
  
  Re-landing with upstream fixes to the layers so they no longer
  need to copy the parameter validation errors to the current
  working directory of the layer generation. Also includes fixes
  for the GCC build.
  
  This hasn't been updated in a while, so there are many changes.
  It should also include better validation for memory barriers.
  
  Also includes updated builds for SPIRV Tools and glslang.
  A few pull requests need to land before landing this in ANGLE.
  
  This second step re-enables Vulkan and includes the updated build.
  
  Includes a workaround for parameter_validation.h no longer being
  auto-generated, and the stale file clobbering the build.
  
  Also includes a fix for an incorrect memory barrier.
