Styled Version of EnergyPlus 8.9.0

Right after 8.9 was released, we applied a new code style to the whole EnergyPlus codebase. To allow easy diff-ing back to 8.9, I am creating this tag. CI didn't build packages for it because of an issue with parsing the output variable lines of code, but this release isn't intended to be used for packaging or release anyway, just a tag.
