fix(material-experimental): add mdc-slider to mdc-theming and mdc-typography

Follow-up to the initial implementation of the mdc-slider prototype. This commit
adds the mdc-slider theme and typography to the `mdc-theming` and `mdc-typography`
entry-points, so that consumers don't need to include the slider styles separately.
