samples: Bluetooth: df: Enable TX of mutliple CTEs in a per adv event

Browse source 
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.
