Move more properties out of exported3_default_prop

This is to remove exported3_default_prop. Contexts of these properties
are changed.

- ro.boot.wificountrycode
This becomes wifi_config_prop

- ro.opengles.version
This becomes graphics_config_prop. Also it's read by various domains, so
graphics_config_prop is now readable from coredomain.

- persist.config.calibration_fac
This becomes camera_calibration_prop. It's only readable by appdomain.
