Add support for SDC slots

[PierrePaul]

Fixes #190

Tests are failing, but it doesn't seem to be related to SDC.
It seems to be related to PhpStormMetaTest. For some reasons though, it doesn't seem to be failing on other PR (maybe because they are failing at the lint step though). Closed PR from two weeks ago seems fine though.

@Chi-teck for some reasons I can't explain, the PhpStormMetaTest used to work fine and stops working on Drupal 11.x after commit https://git.drupalcode.org/project/drupal/-/commit/b72df4495eb2f51d5b87b8ad7018fd913c9eb096

The PhpStormMetaTest assertDatabase is looking for the table 'cache_bootstrap' and can't find it. At this point I'm not sure if this is a new bug in D11 or if expected behavior and PhpStormMetaTest should be updated.

In any case, this should probably be done in a separate issue. If you have some insights (or maybe @weitzman ?), I can take care of this.

My bad, I wasn't resetting my git tree correctly before the tests.
The "bad" commit is actually : https://git.drupalcode.org/project/drupal/-/commit/1584d2c9f2e6718034f5c7c051d702a75a5dae62
Which makes a lot more sense than the other one.

@PierrePaul the tests were broken in 4.x branch as well. @chesn0k has just fixed it and updated this feature branch.
