habanalabs: Mark queue as expecting CB handle or address
Jobs on some queues must be provided with a handle to a driver command buffer object, while for other queues, jobs must be provided with an address to a command buffer. Currently the distinction is done based on the queue type, which is less flexible if the same queue type behaves differently on different types of ASICs. This patch adds a new queue property for this target, which is configured per queue type per ASIC type.
