Research using dblog at tests

Tests passed. Need to double check unnecesate usage of dblog were found before moving to NR.

I made review of dblog module usage in code base, here is a little summary:

For these Kernel tests we can replace dblog module with \Symfony\Component\ErrorHandler\BufferingLogger, or use approach similar to 59ce5ede.

• Drupal\Tests\comment\Kernel\CommentIntegrationTest
• Drupal\Tests\field_ui\Kernel\EntityDisplayTest
• Drupal\Tests\image\Kernel\ImageItemTest
• Drupal\Tests\jsonapi\Kernel\ResourceType\RelatedResourseTypeTest
• !Drupal\KernelTests\Core\Action\EmailActionTest

These functional tests maybe we can also make replacement, but this need to be discused.

• ?Drupal\Tests\big_pipe\Functional\BigPipeTest
• ?Drupal\Tests\media\FunctionalJavascript\MediaSourceOEmbedVideoTest
• ?Drupal\Tests\node\FunctionalNodeCreationTest
• ?Drupal\Tests\system\Functional\Module\ModuleTestBase

These is not obvious, but need dblog module:

• Drupal\Tests\system\Functional\UpdateSystem\UpdateScriptTest can't be removed "$this->assertSession()->linkExists('logged');"
• Drupal\Tests\views\Kernel\Handler\HandlerAllTest test view handler for watchdog table.

I believe these changes need to be done is separate issue, I will create follow-up.

This issue is ready for review.

There is an issue with solving this ✨ Allow kernel tests to fail or expect logged errors Needs work .
