audiocore: Factor from audioio
When nrf pwm audio is introduced, it will be called `audiopwmio`. To enable code sharing with the existing (dac-based) `audioio`, factor the sample and mixer types to `audiocore`. INCOMPATIBLE CHANGE: Now, `Mixer`, `RawSample` and `WaveFile` must be imported from `audiocore`, not `audioio`.crypto-aes
