Bluetooth: host: Add host API to run conn CTE TX params set

Browse source 
Add host API to allow execution of HCI_LE_Set_Connection_CTE_Transmit_-
Parameters HCI command.

The commit also provides a refactored version of hci_df_set_conn_cte_tx-
_param function. The function was aligned to other hci_df_XXX functions
structure with separated parameters validation and preparation of
command object before it is send to controller.
