gve: Define config structs for queue allocation

Queue allocation functions currently can only allocate into priv and
free memory in priv. These new structs would be passed into the queue
functions in a subsequent change to make them capable of returning newly
allocated resources and not just writing them into priv. They also make
it possible to allocate resources for queues with a different config
than that of the currently active queues.
