Posts, Post Types: Introduce item_trashed post type label.

This allows the block editor to announce the correct message when an entity is moved to the Trash.

Original issue from Gutenberg repository:
* [https://github.com/WordPress/gutenberg/issues/19144 #19144 Wrong notification message shown when an entity is moved to trash]
