cbfstool: Add attributes for position and alignment constraints.
Add functionality to cbfstool to generate file attributes for position and alignment constraints. This new feature can be activated with the -g option and will generate, once the option has been enabled, additional attributes for the files where position, xip or alignment was specified.
