planner: improve the generation for record the test cases

[Reminiscent]

What problem does this PR solve?

Issue Number: close #35368

Problem Summary:
Now, if we want to record the test cases result in the planner/core/testdata package, we can use the argument --record when we run the test cases. But it will clear the other test cases' results which have been already recorded. So we should improve the generation for the test cases.

What is changed and how it works?

1. Skip the generation for the other unrelated files.
2. Keep the results for the other unrelated tests in the same file.

Check List

Tests

• Unit test
• Integration test
• Manual test (add detailed scripts or steps below)

1. The original test cases can be passed.
2. The argument --record can be worked.

• No code

Side effects

• Performance regression: Consumes more CPU
• Performance regression: Consumes more Memory
• Breaking backward compatibility

Documentation

• Affects user behaviors
• Contains syntax changes
• Contains variable changes
• Contains experimental features
• Changes MySQL compatibility
