Fix LongLineDeclaration in Kernel tests

This changes about 1300 lines, which is larger than the scope guidelines suggest but this is only formatting changes.

Seems pretty straight forward and the rule would catch any missed one.

Don't see any issue.

Needs a rebase.

Rebsed twice, both were a simple conflict in phpcs.xml. Restoring RTBC

Committed/pushed to 11.x, thanks!
