[fix](load) Preserve routine load CSV header formats

[0AyanamiRei]

What problem does this PR solve?

Issue Number: None

Related PR: None

Problem Summary:

Nereids routine load normalized csv_with_names and csv_with_names_and_types to plain CSV while creating the job, then omitted the header type during task planning. Header rows were consequently parsed as data and counted as errors.

This change preserves the validated CSV header format in job properties and forwards it through the Nereids task to the data description.

Release note

Routine Load now honors csv_with_names and csv_with_names_and_types without treating header rows as data.

Check List (For Author)

• Test

  • Regression test
