7903933: Move sharable items from different generations to a common file

[nizarbenalla]

Please review this patch to move the C_* layouts and the static utility methods into separate classes: LayoutUtils.java and FFMUtils.java, respectively.

• The names could later be personalized through a JSON configuration.
• We can use static imports if the -t option is no used and the files are generated into the default package, in that case we use the classname to call the static methods or use the C_* constants.

Some tests had to be modified slightly, either by adding new static imports or replacing classnames.
