0032738: Configuration, scripts - handle ABI list within iOS building script adm/scripts/ios_build.sh

Variables "toSimulator" and "anAbi" within "ios_custom.sh"
have been replaced by "anAbiList" which can be defined like "iPhoneOS|arm64 iPhoneSimulator|arm64".
Added "toPackFat" option packing multiple architectures into FAT archives.
