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: Fixed improperly set env variable
After the first test using the Mock ICD runs, an environment
variable VK_ICD_FILENAMES is set when previously it did not
exists. The cleanup of that test, rather than deleting the
environment variable, set it to an empty string, which the
Vulkan loader would use for subsequent Vulkan tests, causing
issues with Vulkan not finding the correct extensions.
Had to disable two more tests since they started failing once
those backends were enabled.

Update gl2.h and update entry points.
Some method signatures were updated. Types like GLclampf and GLvoid
were replaced with other equivalents.

D3D: Add perf test for dynamic buffer promotion.
Drawing with a DYNAMIC usage array or element array buffer should
eventually lead to internally switching to a static usage, if the app
doesn't modify the data very often. This perf test simply renders a
bunch of random indexed triangles where both buffers are specified as
DYNAMIC. It should perform just as well as the static usage after a
warm-up period.
