whisper : map token timestamps to original time when VAD is enabled (#3910)
whisper_full_get_token_data().t0/t1 are in the VAD-processed timeline (silences
removed), so they don't line up with the original audio. Add
whisper_full_get_token_t0/t1 that map them back.
A token inside a speech segment is interpolated within it; a token that falls in a
removed inter-segment silence snaps to the nearest boundary, so it never lands in
the middle of a cut-out gap. Without VAD the raw times are returned unchanged.
