With the introduction of `EXPERIMENTAL` and `WARN_EXPERIMENTAL` in
Zephyr all subsys/bluetooth and drivers/bluetooth/hci settings having
`[EXPERIMENTAL]` in their prompt has has been updated to include
`select EXPERIMENTAL` so that developers can enable warnings when
experimental features are enabled.

First implementation of periodic advertising sync filtering
requires existence of Direction Finding Extension in Radio
peripheral.
To add the filtering support for other Nodric SOCs software
based PDU traversing for CTEInfo should be implemented.
In case there is no DFE in Radio peripheral, actual filtering
is done in ULL.
The commit provides necessary changes to previous solution.

Set BT_CTLR_DF_ANT_SWITCH_RX enabled by default.
There is already added implementation that supports
this feature in controller, so it may be enabled by
default.

Add Kconfig option that will enable possiblity to sample CTE attached to
PDUs that have bard CRC. Sampling is based on CTEInfo field available
in received PDU. If radio is able to parse the field correclty then
it will start sampling even the CRC is wrong.

Direction Finding support requires possibility to receive and sample CTE
attached to periodic advertising PDUs. New option will be used to enable
or disable the functionality. New option is introduced to avoid using
double statements checking if BT_CTLR_DF_CTE_RX and BT_CTLR_SYNC_-
-PERIODIC are enabled.

To avid enabling HCI drived debugging, like in other controller source
files, Direction Finding has its own option BT_CTLR_DF_DEBUG_ENABLE.
This gives fine grained control deubgging output.

Remove compilation warning caused by currently not used
hci_df_set_conn_cte_tx_param function.
Code is sorrounded by #ifdef CONFIG_BT_CTLR_DF_CONN_CTE_RSP.
The CONFIG_BT_CTLR_DF_CONN_CTE_RSP is changed to be disabled
by default (until complete implementation of the feature is
provided).

Add initialization of GPIOs that are used for antenna switching.
GPIOs provided to DFE extension in Radio peripheral, to drive
antenna switching, should be initialized in GPIO peripheral beforehand.
The initialization is optional and may be disabled by Kconfig.

Anternna switching should be disabled when CTE Rx is not supported
or disabled. Added missing dependency on BT_CTLR_DF_CTE_RX.

The storage for extra data is required for implementation of
CTE transmission with periodic advertising.
Data required to transmit CTE correctly are compound of two parts:
- PDU field CTEInfo
- radio configuration to transmit actual constant tone at the end
of PDU.
Extra data is a storage required for radio configuration data.
Nevertheless it must be in compliance with content of CTEInfo field.
Because of that extra data is stored as part of lll_adv_pdu and
is double buffered like PDU memory.
Bluetooth 5.1 spec. allows to enable or disable CTE TX
and change CTE TX parameters when periodic advertising is
enabled. Besides that CTE TX settings may be set before periodic
advertising parameters are set. In such situation ll_adv_sync_set
may be not yet created.
To overcome these constraints ULL should store CTE TX
settings and forward them to LLL only when CTE TX is enabled.
Because of above reasons ULL stores CTE TX settings in ll_adv_set.
