Chips away at #14993 and
#16800

Changes made in this PR:
- Update DefaultPhysicalExprAdapter to handle struct column evolution
- Remove use of SchemaAdapter from row filter / predicate pushdown /
late materialization. I believe it was already not doing much here other
than where tests checked specific behavior and had not been updated to
use PhysicalExprAdapter
- Changed projection handling to use `PhysicalExprAdapter` instead of
`SchemaAdapter`
- Kept intermediary `Vec<usize>` so we can use `ProjectionMask::roots`
and punt the complexity of implementing `ProjectionExprs` ->
`ProjectionMask` until a later PR (there is a draft in #18966 of what
that might look like).
