Link selections streams refactor (#4572)

* Explicitly indicate that plotly scatter3d does not support selection region

* Support adding input stream to existing Derived stream

* Don't trigger event when clearing history

This makes it easier to avoid circular update issues

* Add include_region argument to SelectionExpr stream

* Add SelectionExprSequence and CrossFilterSet streams

This pulls out most of the link_selections logic for responding
to linked stream events into Derived/History streams

* Refactor link_selections to use SelectionExprSequence and CrossFilterSet streams

This makes it possible to introspect the output of link_selections and discover the
linked streams that power it

* Remove PlotReset stream from SelectionExprSequence.

This is handled by `link_selection` by clearing history

* Remove stray type hint

* Refactor Plotly callback classes to expose stateless
get_event_data_from_property_update

* hide Plotly HVLine/HVSpan if coords are None

Plotly chooses default values automatically in this case,
so easier to just hide the shapes until there is valid data

* Handle Dash-style axis range event data

e.g.
{'xaxis.range[0]': 1, 'xaxis.range[1]': 4}

instead of
{'xaxis.range': [1, 4]}

* Treat kdims with the same name as identical during decollation

Handles case where dims of the outer objects in an object tree have labels and
dims for inner objects don't.
