Sergey Biryukov 52da9fb6af Code Modernization: Rename the readonly() function to wp_readonly(). ... Since PHP 8.1, `readonly` is a reserved keyword and cannot be used as a function name. In order to avoid PHP parser errors, the `readonly()` function was extracted to a separate file and is now only included conditionally on PHP < 8.1. This commit also: * Moves the tests for the `__checked_selected_helper()` function and all the related functions to their own file. * Switches to named data providers. This makes the output when using the `--testdox` option more descriptive and is helpful when trying to debug which data set from a data provider failed the test. * Improves the tests in question to make them feature-complete and expand test coverage. Props jrf, ayeshrajans, haosun, knutsp, swissspidy, SergeyBiryukov. Fixes #53858.
