This is a reland of f58f69f66b
The whitebox dawn_end2end_tests are updated to link statically against
libdawn_native. This is required because the test link against and use
libdawn_native as sources. It is an error with MSVC to both import and
export symbols from libdawn_native.

This reverts commit f58f69f66b.
Reason for revert: This breaks the MSVC build because the whitebox end2end tests try to both import and export the error injector symbols from libdawn_native

This is the first step for having a fully operational SPVC usage
path. This version of SPVC integration uses SPVC for setting up the
options to the compiler, but a lot of the actual interaction with
spirv-cross is done in Dawn, just via SPVC's compiler object.
Future CLs will migrate more of the spirv-cross interaction to using
the SPVC API, eventually removing the need for Dawn to know about
spirv-cross.

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.

Due the jump within the signal trap used in these fuzzers, local scope
allocations cannot occur while the signal trap is on, otherwise there
is a possibility of leaks. This CL rewrites how the code under test is
run, so that the potentially aborting code is tightly wrapped by
signal trap without any local scope allocations.

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.
