CodeBlocks: Show generated files in non-utility targets
Since 2.6.3 the UTILITY target may have source files. A defect was filed that these files are now visible in the source tree. A fix later removed all generated files from the source tree, regardless of the target type. You can't even include them by using the SOURCES option. This fix adds generated files again, except for the UTILITY target which cluttered the source tree.
Fixes #14272 (closed).
