view-message: add option to view message in background tab

Add a -b flag to the :view command to open messages in a background tab
instead of automatically switching to the new tab after opening. This is
similar to opening browser tabs in the background. More generally, adds
a new function app.NewBackgroundTab so that it is possible to enable other
tabs to be opened in the background in the future.

Implements: https://todo.sr.ht/~rjarry/aerc/266
Changelog-added: Add `-b` flag to the `:view` command to open messages
 in a background tab.
