lib/igt_audio: use double instead of int16_t
In order to be able to generate S32_LE signals, we need a higher precision than
S16_LE. Change the signal generation code to use double instead of int16_t and
introduce a new helper to fill a buffer with S16_LE samples. We already use
arrays of doubles elsewhere (see audio_signal_detect). Similar format-specific
helpers will be added for S32_LE in the future.
