Adding props for Drawer to hide or display the x button when the drawer is opened.

[mason23zh]

What problem does this feature solve?

As for now, once the drawer is opened there is a x button located on the left top corner of the drawer, it would be great if there is an option to choose either to display or hide the x button.

What does the proposed API look like?

Use case: The current x button would take too much space if the drawer component is been used for some mobile devices, a prop that gives control over this x button would make the drawer component easier to work for the smaller screen size.
