In 259611 at main we started serializing runtime-sized arrays. The original implementation
used C-style syntax, and doesn't work with references to arrays, as the generated code
becomes `T& t[1]`, which is parsed as an array of references, and therefore invalid.
This is easily fixed by using the same syntax we use for constant-sized arrays, and
becomes `array<T, 1>& t`.

* Source/WebGPU/WGSL/Metal/MetalFunctionWriter.cpp:
(WGSL::Metal::FunctionDefinitionWriter::visit):
(WGSL::Metal::FunctionDefinitionWriter::visitGlobal):
* Source/WebGPU/WGSL/tests/valid/runtime-sized-array-resource.wgsl: Added.
