This patch implements functionality of  glDrawArraysInstancedBaseInstanceANGLE,
glDrawElementsInstancedBaseVertexBaseInstanceANGLE,
glMultiDrawArraysInstancedBaseInstanceANGLE,
and glMultiDrawElementsInstancedBaseVertexBaseInstanceANGLE

Workaround for OpenGL driver on Mac:
gl_VertexID on Mac with AMD GPU doesn't include baseVertex value.
So replace gl_VertexID with (gl_VertexID + angle_BaseVertex) if any.

Workaround for Vulkan GLSL:
gl_InstanceIndex on Vulkan includes baseInstance. So replace
gl_InstanceIndex with (gl_InstanceIndex - angle_BaseInstance) when
angle_BaseInstance is declared.

Refactors the perf tests to fix the issue of metric and story being

Specifically, does the following:
1. Rolls the version of src/tests/perf_tests/third_party/perf/ to
   Chromium 476dae823269c8d05b544271af97ad1adb0db8ee
2. Switch to using PerfResultReporter instead of PrintResult directly.
3. Split RenderTestParams::suffix into backend and story; backend is
   used as part of the metric, while story is used as the story.
4. Remove the "average" metric that was being automatically reported
   by ANGLEPerfTest, as reported results are automatically averaged.
5. Update the reported metric to more clearly distinguish between
   test, backend, and metric. It is now name_backend.metric. e.g.
   DrawCallPerf_vulkan.wall_time.

Expands existing struct-sampler rewrite to flatten arrays of arrays.
This allows us to support dynamically-uniform array indexing, which is
core in ES 3.2.

Samplers inside (possibly nested) structs are broken apart as before,
and then if the type resulting from merging the array sizes of the field
and its containing structs is an array of array, the array is flattened.

Also adds an offset parameter to functions taking in arrays to account
for this translation.

As a result of outer array sizes leaking into function signatures,
functions taking arrays of different sizes are duplicated according to
how the function is invoked.

if it's through ASSERTs.

Additionally, every transformation is changed such that they do their
validation themselves.  TIntermTraverser::updateTree() performs the
validation, which indirectly validates many of three tree
transformations.  Some of the more ancient transformations that don't
use this function directly call TCompiler::validateAST.

> 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.

This reverts commit 58940f67.

Reason for revert: pixel test failures have been triaged in Gold. Relanding.

Original change's description:
> Revert "Make Mac SystemInfo reflect the currently active GPU on dual GPU machines"
> 
> This reverts commit 720a8bab.
> 
> Reason for revert: pixel test failures per http://crbug.com/984780#c13

> Original change's description:
> > Make Mac SystemInfo reflect the currently active GPU on dual GPU machines
> > 
> > Currently, the GetSystemInfo() function (in gpu_info_util/SystemInfo_mac.mm)
> > on dual GPU Macs always updates the active GPU field of the SystemInfo
> > instance to the first non-Intel GPU it finds. This change overrides the
> > activeGPUIndex field of the SystemInfo instance to reflect the current GPU
> > instead of the non-intel GPU.
