This commit fixes two problems:
1) It includes testing/libfuzzer/libfuzzer_exports.h which exports
the LLVMFuzzerInitialize symbol. On Mac, not doing so causes it
to be removed by the linker.
2) It makes it so that dawn_use_swiftshader is enabled by default
when fuzzing, and enabling swiftshader also enables the Vulkan
backend.

This commit changes wgpu::Device::CreateSwapChain to take an additional
wgpu::Surface argument. Passing nullptr is enough to stay on the
previous swapchain implementation, until the new one is ready.
In order to support both the "old" implementation-based swapchains and
the "new" surface-based swapchains. SwapChainBase is now split into
three abstract classes:
- SwapChainBase that has a virtual method for each of the
wgpu::SwapChain methods.
- OldSwapChainBase that corresponds to the implementation-based
swapchains.
- NewSwapChainBase that will contain the surface-based swapchain
implementation and will eventually just be renamed to SwapChainBase.
The interaction of the surface-based swapchains with the Surface objects
aren't implemented yet, neither are the swapchain methods. Only creation
works.
Validation tests for surface-based swapchain creation are added in the
end2end test target because they need to create OS windows.

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.

- dawn_headers: the new version only exposes the "dawn.h" C API and no
longer includes the C++ API.
- dawncpp: the header and implementation of the C++ API that wraps the
C API. This is unbundled from the rest so the C++ API can be used
with libdawn_proc or other libraries implementing the C API.
- libdawn_proc: A DawnProcTable-backend implementation of the C API.
This is needed because in follow-up commit there will be three libraries
implementing the C API: libdawn_proc that trampolines where we want, and
libdawn_native/wire that don't have trampolines for better perf.

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.
