Message:

Post Thumbnails: Add helper functions for attachment captions.

This adds three new functions for getting/displaying attachment captions:

• wp_get_attachment_caption - Retrieves a caption for a specific attachment.
• get_the_post_thumbnail_caption() - Returns the post thumbnail caption.
• the_post_thumbnail_caption() - Displays the post thumbnail caption.

These are helpful for displaying a caption associated with an image directly
in a template, rather than using the caption shortcode.

This also introduces two new filters:

• wp_get_attachment_caption - Filters the value of wp_get_attachment_caption().
• the_post_thumbnail_caption - Filters the display of the post thumbnail caption.

the_post_thumbnail_caption() is automatically filtered by wptexturize(),
convert_smilies(), and convert_chars() in wp-includes/default-filters.php.

Props flixos90, joemcgill.
Fixes #12235.
