Create a general way to bind objects to `pydeephaven` sessions

[jnumainville]

#5374 added the capability to create shared tickets in pydeephaven, specifically through the SharedTicket class and publish_table method. For deephaven/deephaven-ipywidgets#38 we need a more general publish method exposed, so we can bind other objects to the session, such as charts or dh.ui objects.
