Allow for proper labeling in CPT notices.

[UaMV]

While creating CPTs yesterday, I noticed that notices don't, by default, display proper labeling for the CPT. After digging into the code, I realized that there is the post_updated_messages filter which allows modification of these notices, but, as there is a singular label being defined when a CPT is registered, it could be used to serve proper notices by default. This would allow greater consistency of labeling across the CPT UI.

A first pass at proper notice labeling for CPTs.

Thanks for the ticket @UaMV. This is a dupe of #32532.

Note that injecting the post type name into labels such as in 35095.diff​ isn't viable because the resulting strings aren't translatable.

Ah, thanks! Searched, but hadn't come across that one.

Wait. But the post type name is not being inserted. Rather, a registered label from the post type is being inserted. That should be translatable, yes? no?

Nope, see comment:ticket:17609:3 and comment:ticket:19099:1.

Besides, gettext cannot parse PHP code, only static strings.
