[CrOS Settings] Create ESimManagerListenerBehavior.

Create ESimManagerListenerBehavior, a behavior for observing updates
to the device's eSIM manager, EUICCs and eSIM profiles. This is needed
to update the network settings page whenever its eSIM profiles change
state.

This behavior is required to implement crrev.com/c/2605399, "Install
pending eSIM profile from network settings."
