[D8][WP][UX] Better/advanced Workflow States

[stpaultim]

Description of the need

We are breaking #1475 into two distinct issues. We created #4354 for Forward resvisions and are creating this issue to address the need for Better/advanced Workflow states.

My understanding is that the overall goal of this issue to make it easier for contrib modules to add additional workflow states to revisions/versions than those provided by Backdrop CMS core.

The idea is to make it easier for contrib to add states such as "needs review," "deleted," "pending approval," or whatever states are needed for their custom workflows.

I would love to have someone rewrite or add to this summary of that issue. Please, feel free to review #1475 for more information, noting that much of that issue became focused on the narrower issue of Forward Revisions.

Proposed solution

I don't know, there might be ideas here: #1475

I was just about to write a plea for someone to implement something like this in core or contrib and luckily I found this!

I see now that I reacted when it happened, but then later forgot about it.

I REALLY, REALLY want something like this on our documentation site.

I see that there is no release yet. I will do some testing and comment.

I feel like I would be MUCH more willing to help with documentation, if I could create changes and leave them for someone to review before publishing.

Thanks @herbdool
