You can achive this using admin_init action hook and global $menu.
Here is this code:
add_action('admin_init', 'text_domain_logout_link');
function text_domain_logout_link() {
global $menu;
$menu[9999] = array(__('Logout'), 'manage_options', wp_logout_url());
}
This code goes in function.php file of your active child theme (or theme) or also in any plugin file.
The code is tested and fully functional.

global $menu

Use following code
add_action('admin_menu', 'register_custom_menu_page');
function register_custom_menu_page() {
add_menu_page( 'admin_menu', 'Logout', '0', 'logout', 'users_add_login_logout_link');
}
function users_add_login_logout_link(){ ?>
<div id="dashboard" class="wrap">
<div style="float: left; height: 48px margin: 7px 8px 0 0; width: 48px;">
<br>
</div>
<h2>Log Out</h2>
</div>
<div style="text-align: center;"><img src="put you image link" width="128px" height="128px" /></div>
<div style="text-align: center;">Please wait we are logging you out ...</div>
<br/>
<br/>
<div style="padding: 10px 0; font-size: 25px;"><p>
</div>
<?php
$location = '"Location: ' . wp_logout_url() . '"';
echo '<meta http-equiv="refresh" content="4; url=' . wp_logout_url(home_url()) . '"/>';
}

Another alternative, with a dashicon. Based on this answer.
add_action('admin_menu', 'logout_menu_item');
function logout_menu_item() {
add_menu_page('', 'Logout', 'manage_options', 'logout', '__return_false', 'dashicons-external', 999);
}
add_action('after_setup_theme', 'redirect_loggingout');
function redirect_loggingout() {
if ( isset($_GET['page']) && $_GET['page'] == 'logout' ) {
wp_redirect( wp_logout_url() );
exit();
}
}
