Problem/Motivation
See #2909372-14: [PP-1] Fix 'Drupal.Commenting.VariableComment.MissingVar' coding standard for the reason why this child issue was created and #2909364: [meta] Fix 'Drupal.Commenting.VariableComment' coding standard for general instructions about working on Drupal.Commenting.VariableComment coding standard errors.
This started out fixing only arrays that have default values but changed to fixing all remaining problems discovered by the sniff.
Steps to reproduce
Proposed resolution
Fix all the remaining VariableComments so the sniff can be enabled. This is about 55 changes which keeps the patch a reasonable size for a coding standards issue.
