Scale down a slow index buffer perf test.
This test was slow enough that running 20k iterations might have been
causing a timeout on the Nexus 5.

Try to reduce variance in angle_perftests.
This change does a few things:
- make perf test runner script print % variation instead of stddev
This makes it a bit more clear how much variance there is.
- stabilize CPU in the render perf tests
Setting a thread affinity and priority should stop from switching cores
during the run. Hopefully can prevent background noise from changing
the test results.
- warm up the benchmark with a few iterations
This should hopefully make the test results a bit more stable.
- output a new normalized perf result value
The new result is normalized against the number of iterations. So it
should hopefully be stable even if the number of iterations is changed.
- increases the iteration count in the draw call perf tests.
These tests were completely dominated by SwapBuffers time. Increasing
the iterations per step means we actually are bottlenecked on CPU time
instead.

Vulkan: Enable more perf tests.
Also fixes the check for the correct UINT index extension that wasn't
available on Vulkan. Also includes a workaround for the mock ICD not
implementing buffer state for index ranges.

Add perf test for ushort DrawElements.
The code path in the D3D11 back-end is sigificantly different for
unsigned short indices vs unsigned int. Because of the workaround we
have for the primitive restart index in D3D11, ushort rendering can
be slower.

Run angle_perftests on GLES backend
Adds OPENGLES_NULL configuration
and selects between OPENGL and OPENGLES based on whether building for Android.
Also 2 small changes to get the newly enabled tests to pass on N5X:
1. Require GL_EXT_texture_storage in TexSubImage test
2. Limit numVertexUniforms and numFragmentUniforms to 64 in MatrixUniforms test

D3D11: Minor Optimization to DrawCallNeedsTranslation
Remove IsStreamingIndexData from DrawCallNeedsTranslation since
IsStreamingIndexData is only needed for drawElementsIndirect for fast path.
This change gives about a 4% improvement on the drawElements benchmark for
the D3D11 backend with the null driver.

Add DrawElementsPerf test
This is a follow-up CL for
https://chromium-review.googlesource.com/c/544634/.
In this commit, we add drawElements perf test for d3d9, d3d11 and
OpenGL. Specially, we test DrawElements with unchanged index buffer
every frame and changed index buffer every frame. This is also a
preparation for further remove IndexRange in validation.
Paste a set of data (repeated 30) for reference on Intel skylake
Win10 desktop.
