  [WGSL] Add typing for indexed access on vectors

Reviewed by Myles C. Maxfield.

So far we only supported field access on vectors (e.g. vec2.x) but not indexed
access (e.g. vec2[0]). This extends the typing to add support for that. Just
like our current support for indexed access on arrays, we still don't validate
if the access is out-of-bounds when the index is a constant.

* Source/WebGPU/WGSL/TypeCheck.cpp:
(WGSL::TypeChecker::visit):
* Source/WebGPU/WGSL/tests/invalid/vector.wgsl: Added.
