Remove multipart upload and 10-minute video feature gates

Ship both video upload features unconditionally:

- Multipart upload is now always attempted. The MultipartFallbackError
  path to the legacy single-request upload is unchanged, so a video
  service without multipart support still works. This makes the plain
  'legacy' upload transport unreachable, so drop it from
  VideoUploadTransport and default the telemetry value to 'multipart'.
- The 10-minute duration cap now applies to everyone.
  VIDEO_10_MINUTE_MAX_DURATION_MS is folded into VIDEO_MAX_DURATION_MS,
  and the composer's duration error message no longer branches on the
  gate.
