fix(module:list): remove NgZone dependency (#8439)

This commit removes the `NgZone` dependency from the list item cell. With zone.js becoming
optional, `onStable` won't emit any value when `provideZonelessChangeDetection` is used in
the application config. Instead, it now listens to a subject emission when the content
projection has been initialized.
