Vulkan: Add support for internal cache hit and miss counts
Add a CacheStats class that provides cache hit and miss bookkeeping.
All internal caches make use of this class to keep track of its stats.
This provides a means to profile cache hit ratios a.k.a Vulkan object

Vulkan: Add specialization constants for surface rotation
This plumbing through the specialization constant for surface rotation
from ContextVk to pipeline program creation. It has not been used yet,
so expecting no real functional change. This CL also converts
lineRasterEmulation to use the same specialization constant path as
surface rotation.

Vulkan: Line raster emulation through specialization constant
In preparation for compiling shaders early at link time, this change
reworks line raster emulation such that it uses specialization constants
instead of a preprocessor condition. This means drawing both triangles
and lines with this program will still result in a one-time shader
compilation.
The compilation is still done at draw time in this change.

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.

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.

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 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.
