Dependabot opened PR #2365 to upgrade php-cs-fixer from 2.19.2 to 3.2.1. Changes are required before that can be merged successfully. I believe all the necessary changes are in this PR.
One of the changes is to replace .php_cs.dist with .php-cs-fixer.dist.php. I have made those two identical for this PR so that there will be a meaningful delta listing. After this change is merged, master can be merged into 2365, which will hopefully pass all tests and be mergeable at that point. We can delete the unneeded file after that merge.
Spacing is changed in a handful of source members because of extra stringency in 3.2.1.
