Feature request

What is the expected behavior?

Expose the focusOptions (https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/focus) provided by the underlying HTMLElement.focus API in focus() functions such as MatButton.focus() . This will allow the application to prevent scrolling when the element is focused.

What is the current behavior?

The focusOptions is not exposed.

What are the steps to reproduce?
