    devtool: standard: Handle exporting generated config fragments
    
    The cml1 and ccmake bbclasses generate configuration fragment source
    files that must be exported from the WORKDIR as a source file to be
    preserved across builds. This change adds detection of the current
    recipes inherited classes and for cml1 and ccmake classes checks for the
    specific generated configuration fragment files. These files are then
    exported by devtool and included as SRC_URI files from within the target
    layer.
