Review Comment:
   I'm a bit confused, as we talked like 
   "_keep supports_filters_pushdown so that TableProviders can do Exact pruning 
of filters, e.g. using partition columns._",
    and that is making sense to me now. So, instead, should we pass only 
table_schema's to these `supports_filters_pushdown()` API's at ListingTable 
level? Theory and practice conflict in my mind now
