Fix most common phpcs issues

These are top ones

[x] Drupal.Arrays.Array.CommaLastItem                                      44
[ ] Drupal.Files.LineLength.TooLong                                        30
[x] Generic.PHP.UpperCaseConstant.Found                                    17
[ ] Drupal.Commenting.FunctionComment.MissingReturnComment                 16
[x] Drupal.Commenting.InlineComment.SpacingAfter                           13
[ ] Drupal.Arrays.Array.LongLineDeclaration                                10

I think the ones marked [x] with a fixer would be low hanging fruit to fix and easy to review.
