tests: drivers: clock_control: nrf_onoff_and_bt: Extend test

Extend test to check simple sequential use of BT specific API and
standard onoff API. Test case added as it was initially failing on
nrf54l15. Additionally, increased startup time for nRF54LX were
HFCLK start is combined with tuning and it takes longer.

Added nrf54l15dk//cpuapp to the test.
