/**
* Checks whether ImageCapture supports a specific capture config option.
*
* <p>When capturing images, JPEG related options will be applied. But not all devices can
* support those options. For example, CaptureConfig.OPTION_ROTATION is used to provide the
* target rotation information to the HAL. So that the HAL can rotate the image buffer directly
* and provide the correct orientation information in the embedded exif data. But Huawei Mate 20
* Lite and Honor 9X can't handle the capture rotation option correctly and the embedded exif's
* orientation value is wrong. For these devices, the rotation option can't be used and we should
* calculate the rotation value according to the target rotation setting for the final output
* image. See: b/171492111.
