scons: Make scons aware of changes to cxx_type in param types.
If the cxx_type value changes, then the way the parameter is declared
in the param struct will also change, and the header needs to be
updated. scons would miss this sort of change before because it was only
checking the module the SimObject's source came from. The python names
and types of the parameters could stay the same, but the C++
representation might have changed because of edits somewhere else.
This CL assumes that cxx_type is the only thing that will change and
transparently affect the params struct. I tried making scons sensitive
to the entire ptype which would capture other parameters, but that
didn't work for some reason. This should be pretty safe in general, but
not 100% safe
