Comments: add __get() and __set() to WP_Comment to provide BC for plugins that are grabbing post properties from the comment object due to an (unintended?) side effect of JOINing with the posts table in WP_Comment_Query, see [17667]. 'fields' used to default to *, so the JOIN would grab every field from both tables. #YOLO

Since [34310], these properties no longer exist. We can lazy load them for plugins with the magic methods. 

Fixes #27571.
