Gabe Black e4be93b55f sim: Add some helpers for setting up Signal*Ports in python. ...

The only difference between these types in python are the compatibility
strings which restrict what can connect to what. For ports which are
generally useful like interrupts or resets, they should have port types
with special names and even more restrictive compatibility. For other
ports which are one off signals between components, that would be
overkill, and these helpers will let you make a signal port which is
only restricted to ports which carry the same type of data.

The helpers are intended to look similar to their C++ counterpart
templates, and are functions which take a type signature as a string
as their argument, and return a class which is specialized to use that
type signature. The class itself can be stored, or used immediately.

foo = SignalSourcePort('bool')('A port for the foo signal')
