cmake: Add new generate_inc_file_for_gen_target function

Browse source 
Add a variant on generate_inc_file_for_target in which the user can
specify the target that the generated file will depend on.  This allows
exposing that target to other possible places where a dependency on the
generated file existing might be needed.
