Include an edit link in the table that lists fields

Here is a first pass patch that works for nodes and paragraphs. I will follow up with a patch that supports the rest of the entity types.

This patch actually works. The patch from #3 was attempting to call `$edit_link->toRenderable` and it wasn't necessary.

Another patch that adds the destination parameter to the link so that when you save the any changes made to the field configuration you are returned to the cm doc.

Thank you for the contribution @lexfunk I will try to get to reviewing this in the next couple days.

Hi Lexfunk this is looking pretty good.
Do we need to wrap the return in getFieldEditLink() with a check for the existence of $type_parameter_key?
It looks like $type_parameter_key is only defined if it is a node or a paragraph due to the switch case. Maybe have in intentionally return NULL if $type_parameter_key is empty, so the return can specify Link|null ( rather than Link | void )

I committed your patch @lexfunk and then followed up with a couple minor changes

1. CS cleanup
2. moved the access check into the getFieldEditLink() method.
3. Add the link to the table for sibling fields too.

Thank you for all your work on this Lex. It is a really helpful feature.

This if fixed and will go out with 1.0.24.

This has been released in 1.0.24
