habanalabs: add gaudi2 wait-for-CS support
In Gaudi2 we moved to a different wait for command submission
completion model. Instead of receiving interrupt only on external
queues, we use the device's sync manager to notify us when the
entire command submission finishes.
This enables us to remove the categorization of queues to external
and internal, and treat each queue equally, without the need to parse
and patch any command buffer.
This change also requires refactoring to the IRQ handling of
CS completions.
