Subject: [PATCH 1/2] fix(select): consider value changes via arrow keys on
 closed select as user actions

Currently, the user changing the `md-select` value using the arrow keys on a closed select won't mark the interaction as `isUserInput` in the option's selection event. These change s correct the behavior.

Fixes #5084.
