Due to the way GN target discovery works, glfw would get discovered in
Fuchsia / Android / ChromeOS builds when it isn't supported causing
compilation failures. This changes third_party/BUILD.gn so that glfw
targets are only created on supported platforms. It also changes
dawn_glfw in BUILD.gn to be more robust to building on all platforms.

For some unknown reason, during the Chromium build, the
third_party/dawn/third_party:glfw always get rebuilt even when
nothing actually references is (as is the case for "is_fuchsia ==
true").
This ends up in a build failure, since glfw doesn't support this
platform. See [1] for an example.
This CL is a work-around that makes the library empty for Fuchsia
instead. Note that this is never linked into anything so should
not be an issue for any Chromium-related code either.

The Fuchsia platforms relies on a number of Vulkan extensions
that have not been upstreamed to Khronos yet, and thus are not
part of the official Vulkan headers (i.e. <vulkan/vulkan.h>).
This CL adds a new header under src/common/ that contains these
declarations, extracted from the Fuchsia source tree, and ensures
they are included automatically from <common/vulkan_platform.h>
This is necessary to support certain features when building
Dawn on Fuchsia.
IMPORTANT NOTE: Some of the things declared in this header will
change once everything is upstreamed, which will require updating
the source code using them. For example,
VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_TEMP_ZIRCON_EVENT_BIT_FUCHSIA
Will likely be renamed officially as:
VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_ZIRCON_EVENT_BIT
And will be assigned a new value by Khronos.

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.

This updates the content of third_party/khronos/vulkan
to match the upstream v1.1.115 headers.
+ update third_party:vulkan_headers to define the VK_USE_PLATFORM_XXX
macros directly, since this better matches the upstream BUILD.gn
file behaviour.
NOTE: A better patch would use a DEPS entry to get the Vulkan
headers. That's exactly what [1] does, but fails to
integrate with Chromium due to its messy situation
regarding the use of vulkan headers.
Once the Chromium situation is fixed, it will be possible
to remove third_party/khronos/vulkan entirely and rely
on a DEPS entry.

This completely removes the dependency on glad by generating the GL

This requires adding khrplatform.h so all Khronos dependencies are

Also removes a stray CMakeLists.txt that was still hanging out.

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.

This includes a bunch of fixes for clang warnings in Windows specific
code that was only compiled by MSVC previously. This also tidies up some
BUILD.gn issues on Windows.
This required adding some missing dependencies, splitting public headers
of libdawn_[native|wire] so they aren't hidden in the
libdawn_[native|wire]_sources targets, and making unittests depend on
sources directly instead of static libraries (which is almost equivalent).
As a byproduct, Empty.cpp is no longer needed and is removed.
