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: Add support for VkPipelineCache
The cache is initialized from the application's blob cache and is
occasionally written back to it for disk storage.

Vulkan: Fix bug in reuse of vertex input bindings
Fix bug that used previously used vertex bindings. Now we
use the current program mask to only initialize the vulkan
pipeline with the active vertex input bindings.
+ adjust dEQP expectations

Vulkan: Add a perf test for the Pipeline cache.
This micro-benchmark can be used to measure the performance impact
of changing the Pipeline cache. For instance, we can check if changing
the size of the hash key affects performance significantly.
Also updates the build files so angle_perftests can see vulkan.h, and
makes the Vulkan headers an explicit source set.
This test currently shows that a lot of time is spent in PMurmurHash,
with some time also spent in memcmp.
