Disconnect signals in `ChartView.disable_auto_yrange()` 

Allows for removing resize callbacks for a flow/overlay that you wish to
remove from view (eg. unit volume after dollar volume is up) and thus
less general interaction callback overhead for any plot you don't wish
to show or resize.

Further,
- drop the `autoscale_linked_plots` block for now since with
  multi-view-box overlays each register their own vb resize slots
- pull the graphics object from the chart's `Flow` map inside
  `.maybe_downsample_graphics()`
