This PR fixes a crash that occurs when the terraform import command is used against configuration that has a nested data block defined within a check block.

Essentially, the nested data block still tries to report its checkable status during an import operation. This results in the checks system panicking as it is not expecting that kind of check to be reported.

The fix in this case is just to make the full check block also execute during an import operation. Note, that this behaviour matches the behaviour of other checkable objects. Resource pre and post conditions still execute during the validate operation, they just report warnings instead of errors. As check blocks already only report warnings, making all checkable objects consistent in this case is as simple as turning on check blocks during import.

Fixes #33572

Target Release

1.5.4
