/**
* Form constructor for the comment reply form.
*
* There are several cases that have to be handled, including:
* - replies to comments
* - replies to nodes
* - attempts to reply to nodes that can no longer accept comments
* - respecting access permissions ('access comments', 'post comments', etc.)
*
* The node or comment that is being replied to must appear above the comment
* form to provide the user context while authoring the comment.
*
* @param \Drupal\Core\Entity\EntityInterface $node
* Every comment belongs to a node. This is that node.
* @param $pid
* (optional) Some comments are replies to other comments. In those cases,
* $pid is the parent comment's comment ID. Defaults to NULL.
*
* @return array
* An associative array containing:
* - An array for rendering the node or parent comment.
* - comment_node: If the comment is a reply to the node.
* - comment_parent: If the comment is a reply to another comment.
* - comment_form: The comment form as a renderable array.
