Two streams in Single Stream mode

#### Device:
Pixel 7 Pro

#### Version:
JCA 1.0.0-rc01

#### Issue description:
Based on dumpsys log, it seems like JCA is actually 2 streams, not 1, in case of Single Stream mode.
```
    Stream[0]: Output
      Consumer name: ImageReader-4080x3072f21m4-4182-4
      Dims: 4080 x 3072, format 0x21, dataspace 0x8c20000
...
    Stream[1]: Output
      Consumer name: SurfaceTexture-1-4182-6
      Dims: 1600 x 1200, format 0x23, dataspace 0x8810000
...
```

#### Reproduce steps:
1. Open JCA
2. Set Single Stream mode from settings
3. Use a command like `adb shell dumpsys media.camera | egrep -A 40 "Stream configuration"` to confirm the correct streams are configured.

Extra: Capture an image and record a video to confirm the resolutions.

#### Others:
A major side-effect of this is that JCA has less video recording resolution than supported in single stream, due to accommodating an extra image capture stream.

For example, in the Pixel 7 pro, video recorded with CameraX core-test-app with Preview + VideoCapture being bound is 1026x1920. In JCA single stream case, it's only 720x1280.
