### What problem does this PR solve?
This change extends the `tableAlias` feature from the logical plan layer to
the physical plan layer, enabling table aliases to be preserved throughout the
entire query execution pipeline from SQL parsing to physical execution.
When analyzing query execution plans, especially for complex queries where
the same table appears multiple times with different aliases, it has been
challenging to match scan nodes in the plan back to their corresponding table
references in the original SQL.
