MatButton -> Focus property, or at least Ref property to get the ElementReference

[jweschenfelder]

Describe the feature request I would like to be able to set the focus on a MatButton programmatically. For now, this feature is not available yet. Microsoft offers the method .FocusAsync(), but it is not working with MatButton, it is only working with ElementReference.

Currently, I cannot use the Ref property for the MatButton component as described here: https://www.matblazor.com/Button I would await that Ref works, but it is not a recognized property:

Expected behavior I wish, I could set the current focus on a MatButton or that I can at least get the ElementReference for the DOM element. If I use @ref, it will return the MatButton object, but not the ElementReference for the DOM element.
