scripts: board: common: add new FIT support for all platforms
Adds new FIT support to all platforms to enable internal data support for FIT files. To enable the new internal data support for FIT files, use the normal NETBOX_IMAGE_FIT config param. If a need of an old FIT image support, You can use the NETBOX_IMAGE_FIT_LEGACY config param. In this case an FIT image with old external data will be generated.
