executor, codec: hash join build wrong hash key for ENUM/SET value (#49031)

[ti-chi-bot]

This is an automated cherry-pick of #49031

What problem does this PR solve?

Issue Number: close #48991

Problem Summary:

What changed and how does it work?

When the projection disables the ColumnEvaluator, it will eval the ENUM and parse a new ENUM. But the new ENUM value's value index will be set to 0.

But when we construct the hash value for the join key, we use the value index to seek the string value. So a wrong hash key is constructed.

This pull aims to solve the case.
