  Vulkan: Roll loader/validation layers SDK. (2/2)
  
  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.
  
  Bug: angleproject:2237
