Support plain loggers in DebugExceptions

I have been seeing people setting `Logger` instances for `config.logger`
and it blowing up on `rails/web-console` usage.

Now, I doubt many folks are manually setting `ActionView::Base.logger`,
but given that `DebugExceptions` is running in a pretty fragile
environment already, having it crash (and being silent) in those cases
can be pretty tricky to trace down.

I'm proposing we verify whether the `ActionView::Base.logger` supports
silencing before we try to do it, to save us the headache of tracing it
down.
