Check all non-camera-compat-mode-values.

CAMERA_COMPAT_FREEFORM_UNSPECIFIED was added to match atom logging
format, which shifted other values. To check whether app is in
camera compat mode, both CAMERA_COMPAT_FREEFORM_UNSPECIFIED and
_NONE should be excluded.

Also use enum values instead of pure integers to avoid this issue
in the future.
