[CFE] First pass at internal test utility

This is a first pass at running inlined tests
(seemingly called doctests in for instance python) on internal CFE code.

This is not useful for testing the entire compiler for instance, but
could be useful for utility methods that take simple inputs and provide
simple outputs.

I've added tests to a few tings to try it out.

The syntax for it here is probably overly verbose but we could iterate
on that if need be.

The way it's done is that the test-code is extracted from the comments
and (virtually) "injected" in a weirdly named top level method of the
same file, which is then called from a "fake" main; the whole thing is
compiled to dill and run in an isolate.
(This is an application where making advanced invalidation support
adding top level methods would be great).
