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.

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

Add texture sampling perf test
The test generates a texture containing random data and then blurs it in
a fragment shader using nearest neighbor sampling. The test is
specifically designed to test overhead of GLSL's builtin texture*()
functions that may result from how ANGLE translates them on each backend.
