eb1ca45df7 Fix Vulkan fuzzer on mac_libfuzzer_chrome_asan
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.

f12c9dba6d Add WGPUAdapterProperties and expose it in DawnNative
The dawn_native::Adapter::GetPCIInfo/GetBackendType/GetDeviceType
methods are now deprecated in favor of a method returning a webgpu.h
AdapterProperties structure. Deprecated function are still available to
avoid breaking Chromium or Skia compilation.

This reduces the difference between dawn.json and webgpu.h

3890934033 fuzzing: Create Instance and discover Adapters only once
This patch moves Instance initialization and adapter discovery so that
it is done once globally, and not for every fuzz input. This is to work
around a bug where destructing the instance at the end of a run breaks
when fuzzing with Swiftshader.

470921fe46 Reland "fuzzing: Add supportsErrorInjection option to DawnWireServerFuzzer"
This is a reland of f58f69f66bacefb0aaf78e91b462b5db97cea391

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 option will be used by backends that support error injection so
> that errors can be injected into a "clean" corpus to generate a seed
> corpus with good examples of injected error conditions.

87d3138158 Revert "fuzzing: Add supportsErrorInjection option to DawnWireServerFuzzer"
This reverts commit f58f69f66bacefb0aaf78e91b462b5db97cea391.

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
