Run IWYU (with the new tools) on test simulator code This mixes some manual work (IWYU pragmas, a better solution to the Arduino preprocessor macros problem) with automated running of the tools. At this point, it would be too much work to separate these into distinct commits, and there isn't that much value to doing so. There are still some things we could do to make things more robust, as some of the headers need to be in a certain order, which happens to be in the same sort order used by IWYU (`testing/*` files need to come after certain headers than include `Arduino.h`), but it's probably not worth the clutter of adding an `#if 1` just to stop IWYU from re-ordering them. I tried to get `#pragma push_macro("max")/pop_macro("max")` to work, but ended up getting completely nonsensical compilation errors, so I gave up on it.
