Start handling system-value semantics during lowering
I hadn't been lowering `SV_Position` outputs to `gl_Position`, and had somehow been relying on hidden driver behavior that I guess made things Just Work.
This change adds some infrastructure to handle `SV_` semantics during lowering of an entry point (currently only covering `SV_Position` and `SV_Target`, FWIW).
As a byproduct, this also means that a `VarLayout` stores semantic info, which could conceivably be exposed through reflection data now.
