-----------
[WGSL] Incorrect swizzle validation
https://bugs.webkit.org/show_bug.cgi?id=257378
rdar://109886275
Reviewed by Mike Wyrzykowski.
Swizzle characters need to be checked for bounds, e.g. we can't access vec2.z,
but the original patch was incorrectly checking the offset of the swizzle
against
the size of the resulting vector, not the vector we are loading from.
* Source/WebGPU/WGSL/TypeCheck.cpp:
(WGSL::TypeChecker::vectorFieldAccess):
* Source/WebGPU/WGSL/tests/invalid/vector.wgsl:
* Source/WebGPU/WGSL/tests/valid/swizzle.wgsl: Added.
