Revert "Re-land "Vulkan: Roll loader/validation layers SDK. (2/2)""

This reverts commit 755a9317ff1ec983f2704fc9f4619cac49992960.

Reason for revert: Broke local win build. crbug.com/797253

Original change's description:
> Re-land "Vulkan: Roll loader/validation layers SDK. (2/2)"
> 
> 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.
> 
> Bug: angleproject:2237

ANGLE - Almost Native Graphics Layer Engine

The goal of ANGLE is to allow users of multiple operating systems to seamlessly run WebGL and other OpenGL ES content by translating OpenGL ES API calls to one of the hardware-supported APIs available for that platform. ANGLE currently provides translation from OpenGL ES 2.0 and 3.0 to desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Support for translation from OpenGL ES to Vulkan is underway, and future plans include compute shader support (ES 3.1) and MacOS support.

ANGLE v1.0.772 was certified compliant by passing the ES 2.0.3 conformance tests in October 2011. ANGLE also provides an implementation of the EGL 1.4 specification.

ANGLE is used as the default WebGL backend for both Google Chrome and Mozilla Firefox on Windows platforms. Chrome uses ANGLE for all graphics rendering on Windows, including the accelerated Canvas2D implementation and the Native Client sandbox environment.

Portions of the ANGLE shader compiler are used as a shader validator and translator by WebGL implementations across multiple platforms. It is used on Mac OS X, Linux, and in mobile variants of the browsers. Having one shader validator helps to ensure that a consistent set of GLSL ES shaders are accepted across browsers and platforms. The shader translator can be used to translate shaders to other shading languages, and to optionally apply shader modifications to work around bugs or quirks in the native graphics drivers. The translator targets Desktop GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms.
