For AB devices, support flashing two system partitions for factory use. The normal system image on one partition, but without dex preopt. And a system_other image that just contains the odex files. The dex files will not be stripped out of the system image, in case the second system partition is wiped. Setting BOARD_USES_SYSTEM_OTHER_ODEX := true in the BoardConfig.mk enables this behavior. One can control which directories are placed in system_other by the SYSTEM_OTHER_ODEX_FILTER configuration variable. Currently we default to only copying only app and priv-app odexs.
