Prevent parallel DecompressChunk in queries with LIMIT

When the constraints of a DELETE on a compressed chunks fully cover the batches we can optimize the DELETE to work directly on the compressed batches and skip the expensive...

Add support for array operations to compressed DML

Depends on #6877

Atm this just extracts OpExpr handling into separate function. Stay tuned for more changes in this area.

Since we don't do control flow analysis our object creation tracking can mask potential problems and produce false negatives. The following snippet would not produce a warning about unsafe function...

Improve compressed DML expression pushdown
