Everyone using spirv-cross includes its headers via <spirv_msl.hpp> for
example. Make Dawn match that convention so it can play better with the
setup used by other projects.
Still leave <spirv-cross/spirv_msl.hpp> working for now because it is
used by shaderc_spvc. A follow up CL to that repo will do the same
change.

The range of the Z-coordinate in clipping volume is [-w, w] on OpenGL,
while it is [0, w] on D3D12, Metal and Vulkan.
In this patch, the "fixup_clipspace" flag of SPIRV-Cross is enabled on
OpenGL backend and disabled on D3D12 backend to unify the behaviour of
clip space on all Dawn backends. An end2end test is also added for this
fix.
This patch also fix a bug when clearing depth stencil attachments on
OpenGL backend. Before clearing depth stencil attachments, we should
enable depth stencil writing by properly setting depth and stencil
masks. We do not need to set the depth and stencil masks back because
they will be set again when applying the render pipeline. The newly
added test will fail without this fix when running the test together
with all the end2ends.

This CL adds in fuzzers for SPIRV-Cross for HLSL, GLSL, and MSL
outputs. These fuzzers live in Dawn because there is not appropriate
location in the Chromium source repo for them and it is unlikely they
would be land-able in the SPIRV-Cross repo, because it is not coupled
with Chromium's build system and thus Clusterfuzz so would be
effectively dead code. Dawn depends on this code, but it is also
integrated into the Chromium build system, so this was the best place
I could find for them
The code under fuzz unfortunately uses exceptions/aborting as its
error reporting mechanism. This is an acknowledge short coming and
there are efforts to remove this behaviour. To work around this and
reduce the number of false positives found by the fuzzers, a signal
trap has been implemented which will be removed once the code under
fuzz has been updated.
The trap replaces the existing signal handler and silencing signals
while running the code under test. This allows the code under test to
call abort() and not crash the fuzzing process. Theoretically, only
SIGABRT should need to be trapped, but something is causing the signal
from abort() to be converted to SIGSEGV when running under ASAN.
This signal trap has been tested with the fuzzing/sanitizers by
intentionally inserting bad calls that will occur after a few thousand
test cases. It was confirmed that the fuzzer detected the issue and
stops fuzzing.
The alternate to implementing this signal trap would be to turn on
exceptions for the fuzzer. This was attempted, but proved to be
fruitless due to what was reported as an ODR issue, but couldn't
couldn't be silenced. The likely underlying issue was a pre-built
library or other object being built without exceptions was causing
different versions of symbols or the exception version of the standard
library not being instrumented by ASAN. Given the majority of Chromium
eco-system turns off exceptions, fixing this issue would not be
helpful to the larger community and was looking like it would require
significant effort.

In the DEPS file we are going to use Chromium's mirror of
github.com/KhronosGroup/SPIRV-Cross so we need to adjust .gitmodules to
point to it instead of Kangz/SPIRV-Cross. Also take that opportunity to
roll SPIRV-Cross.
