Add new functions for getting and setting the engine's global time.

* ma_engine_get_time_in_pcm_frames() (replaces ma_engine_get_time())
  * ma_engine_get_time_in_milliseconds()
  * ma_engine_set_time_in_pcm_frames() (replaces ma_engine_set_time())
  * ma_engine_set_time_in_milliseconds()

These changes are consistent with the naming of other time based
functions, eliminates ambiguity and just makes it clearer as to what
you're working with.

ma_engine_get_time() and ma_engine_set_time() have been deprecated.
