Refactor perf tests to fix metric/story swapping
Refactors the perf tests to fix the issue of metric and story being
swapped, which causes issues when trying to convert to histograms.
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.

Make angle::Result an enum.
This moves away from a class type to a value type. This should improve
performance when using angle::Result as a return value. Previously the
generated code would return a pointer instead of a value.
Improves performance in the most targeted microbenchmark by 10%. In
more realistic scanarios it will have a smaller improvement. Also
simplifies the class implementation and usage.
Includes some unrelated code generation changes.

Remove gl::Error.
Removes several TODOs. Only egl::Error remains.
Also slightly decreases binary size.

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.

Add perf test for Error/Result class.
This is a performance test that stresses the Error class. It also is
used in tests for the new Result class.
