New event for CookieAuthenticationEvents when authentication cookie is renewed/refreshed

### Is there an existing issue for this?

### Is your feature request related to a problem? Please describe the problem.

I am currently issuing an additional cookie based on the authenticated user when they sign in, but the problem is that I can't reliably know when the authentication cookie is refresh to issue the additional cookie again.

I checked the `CookieAuthenticationHandler` and seems like the refresh happens in `FinishResponseAsync` which can be overridden, but doesn't really provide the information when/if the refresh happened. Might be possible to detect it by checking the response `Set-Cookie` but that way I don't know the `AuthenticationProperties` of the new cookie.

### Describe the solution you'd like

A new event `OnRefresh`/`OnRenew` in `CookieAuthenticationEvents` that is fired with the new principal+properties somewhere after `AppendResponseCookie` in `FinishResponseAsync`

### Additional context
