When implementing vendor specific HCI APIs and events,
we want to be able to convert between host objects,
handles and back again.
Exposing this API makes that possible.

Fail gracefully if an HCI event of one type arrives for a handle of a
different connection type. The requested types are currently based on
what fields are used, not on the usage context, in order to keep every
correct use so far still working.
A warning is logged if the connection identified by the handle does not
match the requested connection type.

The `bluetooth/common/log.h` and `bluetooth/common/log.c` files have been
removed. Files that were using them have been updated to use
`zephyr/logging/log.h` instead.
Those replacement have been done consequently:
- `/BT_DBG/LOG_DBG/`
- `/BT_ERR/LOG_ERR/`
- `/BT_WARN/LOG_WRN/`
- `/BT_INFO/LOG_INF/`
- `/BT_HEXDUMP_DBG/LOG_HEXDUMP_DBG/`
- `/BT_DBG_OBJ_ID/LOG_DBG_OBJ_ID/`
Also, some files were relying on the `common/log.h` include to include
`zephyr/bluetooth/hci.h`, in those cases the include of `hci.h` has
been added.
For files that were including `common/log.h` but not using any logs,
the include has been removed and not replaced.

There were a bug in a prepare_cl_cte_rx_enable_cmd_params function.
The size of command buffer was wrong when CTE enabled in AoD mode.
The command buffer was extended by param->num_ant_ids, that was
zero in case of AoD. Then a dummy antenna switch pattern was copied
into the command buffer.
That lead to: memory overwrite, and wrong command buffer length.
The command was rejected by Controller.
To fix, use cp->switch_pattern_len that was already assigned with
correct antenna pattern length.

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

In case the direction finding RX is enabled but without Angle
of Arrival functionality enabled, there HCI command buffer
had wrong command length assigned. It didn't take into account
two dummy antenna IDs provided to fulfil requirement from
BT 5.3 Core Vol 4, Part E sections: 7.7.82, 7.7.85.
HCI driver when received such command buffer, didn't handle it
due to wrong command length.

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.

The CTE type is used in two ways by HCI layer:
1) single value representing particular CTE type: AoA, AoD 1 us,
AoD 2 us
2) bit-filed where bits 0-2 represent particular CTE types AoA
AoD 1 us, AoD 2 us
The bit-field is used to inform Controller about allowed types
of CTE, hence single value carries more than one value.
To avoid confusion between these use cases in code that refers
to case 1) all named cte_type (singular form). For case 2)
cte_types (plural form) is used.
There is an enumeration that is used for both cases:
bt_df_cte_type. For cte_type only single value from the
enumeration may be assigned to variable except
BT_DF_CTE_TYPE_NONE and BT_DF_CTE_TYPE_ALL.
For cte_types all enum members may be used. Ocasionally
BT_DF_CTE_TYPE_NONE may be excluded. If that is true,
it is described in code documentation.
Thanks to that applications are released from requirement
to include hci.h header file.

Fix compilation warning in hci_df_set_cl_cte_rx_enable function.
The struct bt_hci_cp_le_set_cl_cte_sampling_enable *cp variable
was used just to evaluate size in bt_hci_cmd_create call.
The variable is moved to prepare_cte_rx_enable_cmd_params
function and size of the buf is evaluated directly from type.
Code is simpler and prepare_cte_rx_enable_cmd_params does not

There was an issue with receiving CTE packets when the time
slot has changed from 2us to 1us. After receiving the packets
when it tries to enable receiving of CTE, the validator
returns EINVAL error.
Source of the problem is "validate_cte_rx_params" function,
it calls DF_AOA_RX_1US_SUPPORT(df_ant_info.switch_sample_rates)
which is expanded to:
((df_ant_info.switch_sample_rates) & BIT((BT_HCI_LE_1US_AOA_RX)))
And due to definition of BT_HCI_LE_1US_AOA_RX in hci.h it will be:
((df_ant_info.switch_sample_rates) & BIT(BIT(2)))
So the BIT operation has executed two times.
