Bluetooth Controller has a vendor specific extensions that allows it
to send IQ report events with IQ samples that are 8 bits or 16 bits
signed integer. To use that functionality, there is added common
handler of vendor specific events.
Vendor specific events handling is prioritized to be done by user
provided event handler. If that is not available, then Host generic
implementation enters.
Added vendor specific events that are handled by common Host code
are BT_HCI_EVT_VS_LE_CONNECTIONLESS_IQ_REPORT and BT_HCI_EVT_VS_LE-
_CONNECTION_IQ_REPORT.
The only difference between regular IQ report events is size of
IQ samples, hence implementation of IQ report events is changed to
use the same user callback. To avoid differentiation of user callbacks
new member sample_type was added to bt_df_per_adv_sync_iq_samples-
_report. Also sample member is changed to be a union, to allow easy
access to IQ samples without type casting.

In case of error in hci_df_prepare_connectionless_iq_report function
e.g. due to wrong periodic advertising sync handle, uninitilized
per_adv_sync and IQ report object were passed by cte_report_cb callback
to an application.
Correct behavior in such situation is to not to cal cte_report_cb callback.

There were no handling of HCI_LE_CTE_Request_Failed event.
The commit adds missing implementation. An application will
be notified about failed request by cte_report_cb. It is the
same callback that is used for reporting collected CTE IQ
samples. The same callback was used to avoid creation new callback.
To give an application possibility to distinguish between regular
IQ samples report and request failed additional member err was added
to bf_df_conn_iq_samples_report structure.
