Add Value Action Menu functionality to single message page

## What?

Add Value Action Menu functionality to single message page. Currently the only way to access value action menu is via the messages widget.

However, there are use cases where one may be reading the message from a single message view page (can get there by clicking on the message ID hyperlink). This may become even more common with the introduction of the investigations feature in graylog security where you can add messages (message IDs) to an investigation and link back to them.

One may still want to perform actions provided by the value action menu, but will be unable to do so.

## Why?

The UX and behavior of a message should look and behave consistently across graylog. One may want or need to use the actions from value action menu via the single message page but will be unable to do so. There isn't any clear or easy way to view the message in a message widget.
