Mark Backman a84930dc3e Skip empty audio frames after filter buffering ...

Audio filters like RNNoise, KrispViva, and AIC return empty bytes while
buffering audio to accumulate their required frame size. These empty
frames were flowing downstream, causing misleading "Empty audio frame
received for STT service" warnings.

Skip the frame in BaseInputTransport when audio is empty, preventing
unnecessary processing in VAD and downstream processors.

Fixes #3517
