owner(ticdc): fix changefeed state is automatically changed bug

[sdojjy]

What problem does this PR solve?

Issue Number: close #8330

What is changed and how it works?

When we handle the error of a stopped changefeed, the changefeed would be set to error state and retried by the owner. This behavior is unexpected. After this PR, TiCDC will not handle stopped changefeed errors and will just log them.

Check List

Tests

• Unit test
• Integration test

Questions

Will it cause performance regression or break compatibility?

Do you need to update user documentation, design documentation or monitoring documentation?

Release note

Fix a bug that causes a stopped changefeed to restart unexpectedly.
