[HLSL] Initializer lists for incomplete arrays failing

[llvm-beanz]

Initialization of incomplete arrays fail because the size of the entity to initialize is undefined which trips over how we iterate the initializers. I need to create an alternate flow to support repeatedly iterating the dest types list to handle unknown array sizes.

Problematic code:

export void fn() {
    int2 Arr[] = {int2(0,1), int2(2,3), int2(4,5)};
}
