Support select multiple input binding

See original GitHub issue

Perhaps we should support a multi-select input binding. Selected options could populate as an array.

A motivating use case is being able to bind Vega-Lite’s multi selection to an input as well (vega/vega-lite#3722).

I like that Vega binds to standard html input elements so I would prefer to use a standard select with the multiple attribute. A consumer an still wrap the multi select in a fancy dropdown with search but by sticking to the native element we guarantee accessibility and reduce code size.

The Bokeh-based Python package Panel appears to have taken the approach of using the standard select with the multiple attribute (at least it seems so based on the look of the widget). Not sure if looking at their approach can be helpful at least conceptually, or if it is too unrelated to how it would be implemented in vega.
