Vulkan: Faster state transitions.
Implements a transition table from Pipeline Cache entry to
state change neighbouring Pipeline Cache entries. We use
a 64-bit mask to do a quick scan over the pipeline desc.
This ends up being a lot faster than doing a full hash
and memcmp over the pipeline description.
Note that there could be future optimizations to this design.
We might keep a hash map of the pipeline transitions instead
of a list. Or use a sorted list. This could speed up the search
when there are many transitions for cache entries. Also we could
skip the transition table and opt to do a full hash when there
are more than a configurable number of dirty states. This might
be a bit faster in some cases. Likely this will be something we
can add performance tests for in the future.
Documentation is also added in a README file for the Vulkan back
end. This will be extended over time.
Improves performance about 30-35% on the VBO state change test.

Re-land "Load entry points dynamically in tests and samples."
Fixes the Android/ChromeOS/Fuchsia builds by using consistent EGL
headers.
This CL adds a dynamic loader generator based on XML files. It also
refactors the entry point generation script to move the XML parsing
into a helper class.
Additionally this includes a new GLES 1.0 base header. The new
header allows for function pointer types and hiding prototypes.
All tests and samples now load ANGLE dynamically. In the future this
will be extended to load entry points from the driver directly when
possible. This will allow us to perform more accurate A/B testing.
The new build configuration leads to some tests having more warnings
applied. The CL includes fixes for the new warnings.

Vulkan: Rename PipelineDesc/Cache to Graphics&
PipelineDesc describes a Vertex-Fragment pipeline and PipelineCache (not
to be confused with vk::PipelineCache) implements a cache of such
pipeline objects.
In preparation for Compute support, these data structures are prefixed
with Graphics.

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.

pipeline with the active vertex input bindings.

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.
