CPT: Display notice after post actions succeed or fail

[aduth]

Currently, there's no indication of success or failure when trashing a post from the custom post type listing screen. The post simply disappears. We should display a notice to inform the user whether their action succeeded or failed.

The immediate disappearance of the post from the list is a bit jarring IMO - this could use an animation to make it more clear what is going on.

Hmm, it may be possible to use React's CSSTransitionGroup component to apply a transition as the post is being removed from the list. I might even imagine a few variations of this to reflect the type of action taking place - a disappearing post on trash, a "stamp of approval" on publish. Maybe I'm getting a bit carried away 😄 cc @hugobaeta

I think for now it should mimic whatever happens for Blog Posts and Pages. If we iterate, we should iterate across all of these.

The experience on those listing pages is already quite different:

The immediate "optimistic" update in the CPT listing screen is what makes me think an animation would help.

The initial goal of this issue is now satisfied, notably by the following related PRs:

• CPT / State: Display trash notice after save request completes successfully #6306
• CPT: Enable publishing drafts from post listing screen #6530
• State / CPT: Create notices middleware for observing actions #6645
• CPT: Enable restoring posts from post actions #6723

There's some room for improvement here around notice text (including more details about the post) and multiple actions, e.g. #6855 . Additional enhancements should be filed as separate issues.
