Bluetooth: controller: Make per adv filtering by CTE cond compilable

The filtering of periodic advertisements by scanner may be not needed
in certain situations e.g. while use of periodic advertising by BT ISO.
To make the code smaller and avoid execution of not needed code the
functionality will be conditionally compilable. It may be enabled
or disabled by use of CONFIG_BT_CTLR_SYNC_PERIODIC_CTE_TYPE_FILTERING
Kconfig option.
