net/mlx5: Expose command polling interface
Add a new interface for commands execution that allows the
caller to wait for the command's completion in a busy-wait
loop (polling mode).
This is useful if we want to execute a command in a polling mode
while the driver is working in events mode for the rest of
the commands.
This interface will be used in the downstream patches.
