Allow setting buffer length for HotwordAudioStreamManager

A HotwordDetectionService can specify a buffer length for each
HotwordAudioStream in the HotwordDetectedResult by adding an int in the
HotwordAudioStream's metadata PersistableBundle, with the key
HotwordAudioStream.KEY_AUDIO_STREAM_COPY_BUFFER_LENGTH_BYTES.

If the value is not specified or is an invalid value, the default buffer
length is 2,560 bytes.
