net/mlx5: fs, move steering common function to fs_cmd.h

As preparation for HW steering support in fs core level, move SW
steering helper function that can be reused by HW steering to fs_cmd.h.
The function mlx5_fs_cmd_is_fw_term_table() checks if a flow table is a
flow steering termination table and so should be handled by FW steering.
