Because we now support calling a function with a `self` parameter directly, we can unconditionally call `operator$(lhs, rhs)` rather than calling `lhs.operator$(rhs)` if the selected operator function happens to be a member function. This makes the logic a bit simpler and the SemIR a bit smaller. We can't do the same for Carbon operators, unfortunately, as we use the member access to trigger impl lookup.
