feat(mat-selection-list): add slide toggle as alternative for checkbox

#### Bug, feature request, or proposal:
feature request

#### What is the expected behavior?
Option lists can have slide toggles instead of checkboxes, as you can see on Android OS.

#### What is the current behavior?
Option lists are only for checkboxes and if you want to create something that has the same look but has a slide toggle instead, you will have to implement by yourself.

#### What is the use-case or motivation for changing an existing behavior?
Its a very common option list format, very used on Android 5~6.

#### Which versions of Angular, Material, OS, TypeScript, browsers are affected?
Material 5.1

#### Is there anything else we should know?
You can find it in Material's guidelines:

Cute sidebar example:
*(inspired by Twitter's PWA, achieved with slide-toggle, mat-list and `::ng-deep`, that's a lot more than I expect to write)*

Inizia esaminando i componenti mat-selection-list e slide-toggle e il modo in cui viene esposto l’attuale comportamento checkbox di option-list. Il lavoro è completato quando gli elenchi di opzioni supportano gli slide toggles come presentazione alternativa, mantenendo il comportamento di selezione previsto, con una copertura per la nuova opzione.
