softdevice_controller: Add SDC include dir globally

The sdc_soc.h header file is now needed in nrfx_glue.h to set-up event
system resource reservations. This requires the header file to be
available globally within the build system.

Without this change, external libraries that transitively include
nrfx_glue.h through zephyr/kernel.h cannot be built. One of such
libraries is Matter.
