cbfstool: Add attributes for position and alignment constraints.

Browse Source 
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.
