Message:

REST API: Confirm the parent post object of an attachment exists in WP_REST_Posts_Controller::check_read_permission().

Avoid a PHP Error when attempting to embed the parent post of an attachment, when the parent post ID is invalid. Instead check if the parent post object exists before checking the read permission for the parent post.

Props GhostToast.
Fixes #39881.
