rename zc_owned_liveliness_get_options_t to zc_liveliness_get_options_t

Describe the release item

The owned prefix is intended to mark structures which holds reference to external memory / resource. They should be either "moved" or "loaned", keeping single instance responsable for deletion of the data.
This is not the case for options structure - it can be copied freely

Also it's need to be checked, are we going to support this in zenoh-pico? If yes, it prefix should be just z_
