vkd3d-shader/hlsl: Add a helper for unary arithmetic operations.

Browse Source 
The helper doesn't do much, but it is useful to mark operations as
arithmetic as opposed to other categories (like bitwise and boolean),
which have a different treatment.

It also saves an explicit variable to most callers, which can directly
pass the argument node instead of creating an array.
