test,ut: add long flag for tests and adopt long flag in ut tool

[YangKeao]

What problem does this PR solve?

Issue Number: close #58491

Problem Summary:

We have written some long time go tests. It'd be better to provide a tool to run it.

What changed and how does it work?

1. Add a -long flag to the tests.
2. Modify the ut to support running these long tests.
3. Modify the log of TTL to have richer information.

The simplest way to try this PR is to run the following commands:

make tools/bin/ut
./tools/bin/ut run --long --race

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.
    This PR only modifies test and log.
