spa: {libcamera,v4l2}: device: remove params

Browse source 
No params are implemented, so remove them from the emitted `spa_device_info`.
For v4l2, `n_params` was already set to 0 in 938e2b1451
("v4l2: profiles params are not implement yet"), effectively removing them.

No implementation has materialized in the last 5 years, so remove them
altogether, and do the same in the libcamera plugin as well.
