cmake: nrfxlib_calculate_lib_path add NS_PROVIDED to allow non-secure…

… libs

The `nrfxlib_calculate_lib_path` cmake function is given additional
parameter `NS_PROVIDED`. This parameter allows users of this function
to use non-secure libraries if necessary.

The support is added for nrf54l15 SoC only, but can be easily extended
to other SoCs if needed.
