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. Original change's description: > fuzzing: Add supportsErrorInjection option to DawnWireServerFuzzer > > 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. > > Bug: dawn:295 > Change-Id: I837acdde6dd4274adb56edf8e4307427f8d6333b > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/14681 > Reviewed-by: Corentin Wallez <cwallez@chromium.org> > Commit-Queue: Austin Eng <enga@chromium.org> Bug: dawn:295 Change-Id: Ifa092d28aa7ac57cfb197aa4daeb8408f8036d4a Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/14820 Reviewed-by: Kai Ninomiya <kainino@chromium.org> Commit-Queue: Austin Eng <enga@chromium.org>
