exynos: sthal: Import `sound_trigger_notify_ahal_record_status` from newer sthal

* This is used to explicitly stop sthal to prevent concurrent input,
  which is not supported.
* This is also found on 9830 stock sthal, which is a version similar
  to what we already have here.
* From https://gitlab.com/Linaro/96boards/e850-96/platform/vendor/samsung_slsi/-/blob/android13-e850-96/exynos/audio/sthal/unified/v1/sound_trigger_hw.c
