vkd3d-shader/hlsl: Add helpers for binary arithmetic operations.
This commit moves the logic for casting operands to a common type out of add_expr, so that different helpers can use different logics (corresponding to the different typing rules used by e.g. arithmetic, comparison or bitwise operations).
