Reland "Vulkan: Use VK repos' internal BUILD.gn files"

This is a reland of 552f5fcb0d8fcc615856ce3b678190e1cbdd38e6
There was a missing build dependence causing a build no-op
issue which has now been fixed in the upstream Vulkan Validation
Layer repo.

Primary workaround that need to be re-visted and fixed are:
1. Disabled validation layers on 32-bit Windows
2. Disabled validation layers on 32-bit Android
3. Disabled DebugUtils on Android, using DebugReport instead
4. Using custom VK Loader branch to avoid WDK dependence

Original change's description:
> Vulkan: Use VK repos' internal BUILD.gn files
>
> This retires custom BUILD.gn files for the Vulkan Headers, Tools,
> Validation-Layers, and Loader repos. They now have integrated BUILD.gn
> files so switched ANGLE to use those by default.
> Also Validation Layer, Loader, and Tools repos no longer uses codegen
> so this speeds up the build overall.
> Switched over from old VK_LAYER_LUNARG_standard_validation meta-layer
> to VK_LAYER_KHRONOS_validation unified layer.
>
> This changes includes a temporary workaround to the Vulkan-Loader repo
> to remove its Window's build dependence on WDK. There are plans to
> remove that depenedence in Loader master, but until then we can use
> our custom branch workaround.
> It also includes a custom branch for validation layers that includes
> some build fixes for ANGLE.
> Finally, the layers were crashing on Android when attempting to use
> DebugUtils extension so forcing DebugReport on Android for now.

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.
