AudioService: do not log sound effects in audio dumpsys

"audio" dumpsys captures the logs from PlaybackActivityMonitor.
This includes the activity of the SoundPool in AudioService which
handles the sounds effects for the UI, such as touchsounds. But
with touchsounds enabled, too many important player logs are lost
as UI playback events fill the rolling window of logs.
  The fix consists in SoundEffectsHelper giving a handle of the
PlayerBase used for effect playback to AudioService, which then
tells PlaybackActivityMonitor to not log playback events for this
player.

Bug: 236983951
Test: with touch sounds enabled, verify events absent from dumpsys audio
