configurejson2cmake: Use a context manager for file special handling

One can now write
    with special_cased_file("base/dir", "foo.txt") as fh:
        do_something(fh)

This makes the code of processJson a bit clearer, and it allows us to
easily add more files that support the special handling comments.
