Revert "fuzzing: Add supportsErrorInjection option to DawnWireServerFuzzer"

Browse Source 
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

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.
>
