[Android] Flash light turn off when its used with frameprocessor🐛

[ravirajcm]

What were you trying to do?

I am trying to use with frameprocessor also setting torch as 'on' with "useScanBarcodes" as QR to read QR codes.
But as soon as it detect QR it turn of the flash light even I have torch set as 'on'.

Reproduceable Code

<Camera
        ref={CameraRef}
        torch={flash}
        device={device}
        frameProcessor={frameProcessor}
        frameProcessorFps={5}
        isActive={!shouldPauseCamera}
      />

What happened instead?

It should keep torch on when torch='on' and off when torch='off'

Hey! I've rewritten the entire Android codebase of VisionCamera from CameraX to Camera2 in the efforts of ✨ VisionCamera V3.

I just now completed the Camera2 rewrite and I believe the core structure is running, but there might be some edge cases to iron out. Can you try and test the PR #1674 for me to see if you can still reproduce this issue here?

Here's an instruction on how you can test that: #1674 (comment)

If the issue cannot be reproduced with that version/PR anymore, then hoorayy, I fixed it! 🎉
Otherwise please let me know and I'll keep this issue open to keep track of it.

Thank you!
