radv: Only set rt stack size for dynamic stacks

When using a static callable stack, the required scratch has already
been allocated.
Dynamic stacks are located at the end of scratch memory
and are allocated on demand using radv_set_rt_stack_size.
Static stacks live at the start of scratch memory and are allocated in
create_rt_shader by setting scratch_size.
