rowcodec: use array type to decode index value

[YangKeao]

What problem does this PR solve?

Issue Number: close #49680

Problem Summary:

For multi-valued index, we should use the ArrayType to decode the restore data.

What changed and how does it work?

Use the ArrayType rather the direct GetType to decode the restore data. The GetType will give JSON, but we expect the internal type (e.g. unsigned integer, string...).

Check List

Tests

• Unit test
• Integration test
• Manual test (add detailed scripts or steps below)
• No need to test

  • I checked and no code files have been changed.

Release note

Fix the issue that the compound index of multi-valued index and any other non-binary string cannot be inserted.
