fix(SUP-37490): Align captions with clipTo/SeekFrom Values in PlayMan…

…ifest

### Description of the Changes

If sources.seekFrom or sources.clipTo is set
- Ignore the manifest text tracks, which will cause the playkit player
to add external text tracks according to the getPlaybackContext captions
metadata
- Pass seekFrom and clipTo to the playkit player so that it will filter
and shift the caption cues according to the new time range
