fix(elevation): limit elevation transition to box-shadow and opacity

`transition-property: inherit` was causing issues where doing `visiblity: hidden` would animate with the shadow of the button. This change makes it such that we set the default properties to `box-shadow, opacity` on host so that it is still configuratble by the consumer of md-elevation.
