Review Comment:
Previously, schema already pruned without constant columns is passed into
ORCIterable for its filter logic.
However, this fails here when trying to bind the constant column filters to
it (as they are not in the schema). This makes it so that we prune out
constant columns only when we need it, but we keep original schema for the
binding.
