Which issue does this PR close?

Closes #659

Rationale for this change

This PR moves the final expressions (NegativeExpr, UnboundColumn, and CheckOverflow) to the spark-expr crate.

The only expressions remaining in core are the bloom filter expressions, which depend on the parquet package, and subquery, which depends on JNI. I think we can leave these ones in core.

What changes are included in this PR?

  • Move NegativeExpr, UnboundColumn, and CheckOverflow from core to spark-expr
  • Remove datafusion subpackage, so that operators and expression are directly under execution (we previously had two operators packages)
  • Move shuffle_writer to execution::shuffle package
  • Rename CometExpandExec to ExpandExec for consistency with other exec naming

How are these changes tested?
