term: ignore redraw events when not visible

Another attempt at fixing the high CPU usage when terminal tabs are
running interactive tui applications and the message list tab is
selected.

There are cases where a terminal widget can be visible but not focused
(composer, message viewer, attachment selector, etc.). Define a new
Visible interface with a single Show() method. Call that method when
changing tabs to make sure that terminal widget content events only
trigger redraws when they are visible.
