compress/mlx5: support timestamp format

This patch adds support for the timestamp format settings for
the receive and send queues. If the firmware version x.30.1000
or above is installed and the NIC timestamps are configured
with the real-time format, the default zero values for newly
added fields cause the queue creation to fail.

The patch queries the timestamp formats supported by the hardware
and sets the configuration values in queue context accordingly.
