Add View Post link to Admin Bar of Edit Comments page when viewing comments for a single post.

[Otto42]

When viewing the comments page for a single post, such as this:

/wp-admin/edit-comments.php?p=123

The admin bar should have a "View Post" link to view that post specifically. It helps with context to be able to view the post without having to look for the link. This is similar to the View Post link in the Editor or whenever otherwise viewing a single post.

First draft patch to add a simple link attached.

This is a request from me! Would love if we can get this tweak in.

50312.diff​ is a good start, but there is an existing code for displaying the "View Post" link that respects the post type object's public and show_in_admin_bar properties, as well as the post status. So it seems better to reuse that existing code instead of duplicating it. Commit incoming.

Toolbar: Display a "View Post" link when viewing comments for a single post on Comments screen.

Props Otto42, matt, SergeyBiryukov.
Fixes #50312.

Confirmed with @SergeyBiryukov that the DocBlock above the function should be updated with the added global. He says another small commit is expected.

Follow-up to [47903].
