[robotpy] Run wpiformat on non-python files

[pjreiniger]

Offline discussion makes it seem like @virtuald might not love this, but I figured I would at least make the PR. This turns the styleguide on for the non-python robotpy files. The overwhelming amount of changes were related to whitespace, followed by some IWYU for standard library headers.

Python files are excluded because I think import order matters for some of them, and some tests cases are currently just "make sure this can be imported".

I broke it down into a a couple of commits to make the changes more ovbious

1. Update the styleguide.
2. Run the styleguide, which fails because of 3 below. However this includes pretty much all of the whitespace changes
3. Update header / template includes to have #pragma once. This allows wpiformat to get further along in the process
4. Fix all of the warnings. Mostly IWYU, but also some c-style casts and single arg constructors should be explicit
5. Rerun the formatter to clean up the whitespace from 4
6. Fixup clang-tidy warnings. Mostly use braces for one line if statements and collapsing nested namespaces

Some of the include order issues can be resolved with tweaks to the .styleguide file, but that's all getting replaced in #8350 anyway.

For python? Thats what I meant in reference to the import order mattering. I'm sure there is a way to disable the linter check anyway, but I figured it might be more acceptable to Dustin to just run it on these (I assume) not very frequently touched c++ files
