Camera: Avoid latency accumulation when syncing preview to vsync

Currently if the capture intervals deviate from vsync intervals by more
than 5%, reset the captureToPresent offset. This could be problematic
when the camera capture intervals switches frequently between within 5%
threshold and outside 5% thread, because each time we reset the offset,
it could increase resulting in the overall latency become larger
and larger.

- Distinguish between fixed FPS and variable FPS
  - For fixed FPS, if the frame duration is roughly aligned with display
    refresh rate, use the current logic by enforcing a minimum frame
    interval.
  - For variable FPS, or fixed FPS deviating from display refresh rate,
    simply find the closest timestamp in the vsync timeline.
- If we fail to find a presentation timestamp larger than the
  previous frame, manually increase one vsync interval so that we don't
  drop frame.
