Added implementation for calling AoC decoder every 20ms from IAudioPlayerNode to avoid timing issue on AoC side when SID packets are flowing every 160ms when there is silence in call.

Fix: 275528243

Test: Tested with device and confirmed from logs that decoder is called
even no data in jitter buffer
