Try the following steps first and then recheck if you find the template dropdown in the Page Attributes widget:
i. Change your theme to twentyfifteen.
ii. Create a php file named new_template.php and place that file inside twentyfifteen directory, make sure that functions.php is also present in the same directory.
iii. Paste the following code in the file:
<?php
/*
Template Name: Full-width layout
*/
