[WGSL] Generate the correct code for arrayLength
https://bugs.webkit.org/show_bug.cgi?id=262703
rdar://116524838
Reviewed by Mike Wyrzykowski.
As of 268884@main, the API now exposes the size of runtime-sized arrays at the
end of the argument buffer. This patch updates the compiler to match this
argument
buffer layout and rewrite calls to arrayLength to read these sizes.
* Source/WebGPU/WGSL/GlobalVariableRewriter.cpp:
(WGSL::RewriteGlobalVariables::getPacking):
(WGSL::RewriteGlobalVariables::collectGlobals):
(WGSL::RewriteGlobalVariables::containsRuntimeArray):
(WGSL::RewriteGlobalVariables::packArrayType):
* Source/WebGPU/WGSL/Metal/MetalFunctionWriter.cpp:
(WGSL::Metal::emitArrayLength):
(WGSL::Metal::FunctionDefinitionWriter::visit):
* Source/WebGPU/WGSL/tests/valid/array-length.wgsl: Added.
