   ### Is your feature request related to a problem or challenge?
   
   PR https://github.com/apache/arrow-datafusion/pull/8126 updates FilterExec 
statistics method so that it will assume a highly unselective filter in the 
case where it is not possible to estimate the output cardinality of the filter.
   
   It is hard-coded to assume that no rows are filtered out. It would be better 
to make this configurable, so that users can select a default filter 
selectivity value between 0.0 (selects no rows) and 1.0 (selects all rows).
   
   ### Describe the solution you'd like
   
   Add a new configuration option and plumb it through to FilterExec.
   
   ### Describe alternatives you've considered
   
   _No response_
   
   ### Additional context
