fix(material-experimental/mdc-progress-spinner): indeterminate animat…

…ion not working

Seems like a regression from angular#21359. We can't use `:not` to apply the animation
styles, because MDC's mixins target `.mdc-progress-spinner`, rather than `&`.

These changes use the same manual approach as other components to disable
the animations.
