This reverts commit d09317c0b59560ffe94746de37efb729837d62ff.
Reason for revert: Breaks chromium build. See: crbug.com/tint/970
Bug: tint:970
Original change's description:
> Generate shader corpora for fuzzers
>
> Adds scripts that generated corpora of WGSL and SPIR-V shaders for
> the tint fuzzers, from test cases in the repository.
>
> Fixed: tint:966
