 LIBRETRO: Pace audio generation against wall time, not frame count (#7742)

 audio_run() emits a fixed sample_rate/frame_rate samples per call. As
 it runs once per retro_run(), the output rate follows the achieved
 call rate rather than real time: a frontend running below frame_rate
 underproduces and the audio buffer underruns (crackle), while one
 running above overproduces. Video is already frame-locked; audio was
 not.

 Derive the per-call count from the wall-clock time elapsed since the
 previous call (cpu_features_get_time_usec()), so average production
 stays at sample_rate regardless of the retro_run() cadence. Bound the
 batch to the mix buffer size so a long stall (content load,
 save-state) cannot request a multi-second batch. The fractional-sample
 remainder is preserved, and a vsync-locked frontend gets the same
 per-frame count as before.
