This is part of the migration to use `BoundExpression` thought vortex internals. #9120 ## Summary - carry bound projections and filters through scan plans and `LayoutReader` evaluation - use the bound partitioner from #9157 in struct, row-index, and dictionary readers - cache and reuse exact bound partition trees across row splits ## Break LayoutReader api not take a `BoundExpression` it should be easy to make one with `Expression::bind` --------- Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>
