Direction finding samples had dependency on KConfig option defined
in Controller. That caused a problem for split builds where
an application and host are not part of the same binary as
controller. The code dependend on the Kconfig option
was always disabled.
To fix that issue new Kconfig options were introduced to
Host. The dependency is removed. Unwanted features may stil be
disabled and samples binaier will be smaller.
The commit aligns all direction finding samples code.

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.

Since periodic advertising chains are available there is
a possibility to send multiple PDUs including CTE in
a periodic advertising event.
This commit enables such functionality in direction finding
transmitter sample.

Add an application that uses Direction Finding API for
transmission of CTE in connectionless mode (periodic adverising PDUs).
