Bug 295253 – REGRESSION ( 296795@main): [ Sequoia Release WK2 arm64 ] 8X http/tests/webgpu/webgpu/shader are consistent failures

• Component: WebGPU
• Status: RESOLVED FIXED

Description:
http/tests/webgpu/webgpu/shader/execution/expression/binary/bitwise_shift.html
http/tests/webgpu/webgpu/shader/validation/expression/access/array.html
http/tests/webgpu/webgpu/shader/validation/expression/access/matrix.html

http/tests/webgpu/webgpu/shader/validation/shader_io/workgroup_size.html
http/tests/webgpu/webgpu/shader/validation/types/matrix.html

all 8 test are consistent failures  on Sequoia WK2 arm64 Release due WGSL spec conformance issues in the shader compiler after changes on 296795@main
