Sends camera errors back to the developer via the onCameraError callback stream when the camera fails to take a picture to help developers better handle encountering issues while the user is taking a picture.

Fixes flutter/flutter#153091.

Code Review

This pull request improves error handling in camera_android_camerax by providing more descriptive error messages when an image capture fails. The changes introduce a mechanism to send these detailed errors back to the developer via the onCameraError callback stream. This is accomplished by passing the SystemServicesManager to the takePicture method, which is then used within the onError callback to report specific error descriptions based on the ImageCaptureException code. The implementation includes a new helper method to map error codes to human-readable messages. All related tests have been updated to cover this new functionality. The changes are logical and well-implemented. I have one minor suggestion to improve code clarity in the new error handling logic.

Can you update these test cases to make sure that at least one of the new error message is coming though end to end?
