Bluetooth: Controller: fixed native_sim bluetooth tests

the tests started failing after recent nrfxlib update
(PR 25481) adding dependency on nrfx.
This commit fixes the tests by providing nrfx.h stub
for native_sim tests which doesn't require any additional
dependencies and only provides macros needed by the tests.
