[WebGPU] Shader validation lacks VS:VS memory buffer support
https://bugs.webkit.org/show_bug.cgi?id=291867
rdar://149572896
Reviewed by Tadeu Zagallo.
VS:VS memory barriers don't appear to work when shader validation is enabled on
iOS,
this was previously worked around for the general case but there is still an
issue
for indirect indexed validation which uses a two pass validation mechanism.
* LayoutTests/fast/webgpu/nocrash/fuzz-291867-expected.txt: Added.
* LayoutTests/fast/webgpu/nocrash/fuzz-291867.html: Added.
Add regression test.
* Source/WebGPU/WebGPU/RenderPassEncoder.mm:
(WebGPU::RenderPassEncoder::emitMemoryBarrier):
(WebGPU::RenderPassEncoder::clampIndirectIndexBufferToValidValues):
Split pass within validator as needed.
