Subject: [PATCH] fix(card): unable to override elevation

Fixes an issue that prevents users from overriding the elevation of cards. The issue was introduced with the switch to the `mat-` prefix which changed the styling of cards from an element selector to a class, which has a higher specificity than the elevation classes. This change only adds the card shadow if it doesn't have an elevation class.

Fixes #3123.
