bluetooth: controller: Use new SDC variants for nRF54L

SDC library variants corresponding to BT_LL_SOFTDEVICE_PERIPHERAL and
BT_LL_SOFTDEVICE_CENTRAL have now been added for the nRF54L series.
These libraries have a lower NVM and RAM usage and are intended for
applications requiring a basic single-role BLE feature set.

Adjust the Kconfig dependencies so these variants get selected according
to the same criteria as the existing nRF52 SDC variants.
