Widgets: Allow `WP_Widget` subclass instances (objects) to be registered/unregistered in addition to `WP_Widget` subclass names (strings).

Allows widgets to be registered which rely on dependency injection. Also will allow for new widget types to be created dynamically (e.g. a Recent Posts widget for each registered post type).

See #35990.
Props mdwheele, PeterRKnight, westonruter.
Fixes #28216.
