Forked from #48123.

Describe the problem

In TestJobBackedSeqChunkProvider, (sql/row/expr_walker_test.go), an eval.Context is instantiated near the top with keys.TODOSQLCodec. This is incorrect.

Expected behavior

Instead, the test should bind the eval.Context to the SQLCodec coming from the TestServer.

(After #76582, this will be automatically and probabilistically assinged to either a system tenant codec or a secondary tenant codec.)
