Camera2: Inverted Colors in preview

[simonschmeisser]

Currently the colors in camera preview are inverted.

For Xperia 10 III camera2 reports the following supported formats:

10-13 20:23:08.170  4552   942 I DroidMediaCamera: format 32 20  AIMAGE_FORMAT_RAW16
10-13 20:23:08.170  4552   942 I DroidMediaCamera: format 34 22  AIMAGE_FORMAT_PRIVATE
10-13 20:23:08.170  4552   942 I DroidMediaCamera: format 35 23  AIMAGE_FORMAT_YUV_420_888
10-13 20:23:08.170  4552   942 I DroidMediaCamera: format 36 24  AIMAGE_FORMAT_RAW_PRIVATE
10-13 20:23:08.170  4552   942 I DroidMediaCamera: format 37 25  AIMAGE_FORMAT_RAW10
10-13 20:23:08.170  4552   942 I DroidMediaCamera: format 256 100 AIMAGE_FORMAT_JPEG

@mal dropped AIMAGE_FORMAT_YUV_420_888 in some places but commented it out, commenting it back in does not make it work unfortunately

Fun fact: I reverted to camera1 and while sf-camera and fennec browser (via android app support) show the correct colors, sf-browser does not. It has the inverted colors on master/camera1.

I managed to find a bit hacky way to get the colors correct on Xperia 10 III but needs to be tested it doesn't break any other devices.

I tested your latest branch and it looks good here!
