[AUDIO] Use device native sample rates (#1660)

* Init MinAudio to a sample rate of 0 to let the device pick the rate.
Read the rate from the device after it starts up.
Convert AUDIO_DEVICE_SAMPLE_RATE from a #def into an int, that is set from the device's rate
Set all sample systems to use the AUDIO_DEVICE_SAMPLE_RATE as the target rate to minimize resampling.

* use device sample rate instead of separate var
let config define a device sample rate if it wants to, but let the default be 0 for native rate.

* Don't use fixed sample rates for tracker files.
Remove config default audio buffer size and replace with a function that computes one for a reasonable frame rate at the output sample rate.
