ccpp_prebuild.py: speed up recompiling unchanged code (again)

[climbfuji]

This PR fixes an issue that has come up just recently due to unrelated build changes in the UFS. When recompiling the same, unchanged code, the auto-generated caps as well as the cmake include files can change and trigger a full recompile. While it is beyond my understanding why this didn't happen before, the solution is to make the framework more robust against such external changes:

Replace regular Python dictionaries with ordered dictionaries, sort lists where needed to avoid differences in the auto-generated code when recompiling the same code. Also: sanitize formatting in a few places. No code/answer changes.

I'm not sure why the output should have changed if the symbol names did not (I thought they came out in dictionary sort order) but I don't see anything wrong with these changes.

Thanks for the quick review. Yes, at this point I don't want to spend too much time investigating a spurious problem that I can fix by simply replacing all {} with Collections.OrderedDict().
