Remove deprecated code in migration system

I removed deprecated code according:
- https://www.drupal.org/node/3282894 →
- https://www.drupal.org/node/3277306 →

Opened MR.

Appears to have phpcs error.

Updated tests.
Here still one error, but it corresponded to Drupal\Tests\block\Functional\BlockCacheTest::testCachePerRole. Should we check and fix it in current issue?

Seems to have one more in migrate module for Migrate.php

Searched for deprecation and drupal:11.0

Thanks, believe this is good now

I've added some comments to the MR - one of the deprecation removal is a bit more complex than just removing code.

pradhumanjain2311 → made their first commit to this issue’s fork.

Done

Feedback appears to be addressed.

The $expand deprecation removal looks good now. I think though that we need to add a CR here and properly deprecate passing in the $expand parameter. It's the deprecation dance that takes two majors...

Added the CR and updated the deprecation message.

CR reads straight to the point.

Committed 166f3a3 and pushed to 11.x. Thanks!
