It is not. It applies to all parallel regions. We still use the variadic call on the CPU but we can now replace it with a non-variadic interface.

We'll keep the old interface (kmpc_fork_call) for the host (libomp) and code that uses it will continue to work. New code will use it also in a compatible way
because we change caller and callee of kmpc_fork_call to adjust for the aggregate. This will also hold as the new non-variadic interface is introduced.

The device side is simpler, we are only compatible with a device runtime that machtes (as we link it into the app), so there is no compatibility issue to be expected.
