This aims to bring more consistency to the test suite, as the vast majority of data providers already use that prefix. Includes moving some data providers next to the tests they are used in. Follow-up to [55464]. See #57841. git-svn-id: https://develop.svn.wordpress.org/trunk@55562 602fd350-edb4-49c9-b593-d223f7449a82
