`ZipArchive` can fail to validate ZIP files correctly and report valid files as invalid. This introduces a fallback to `PclZip` to check validity of files if `ZipArchive` fails them.
This introduces the new function `wp_zip_file_is_valid()` to validate archives.

In [56689], a ZIP file is needed in `tests/phpunit/data/filesystem/` but wasn't included in the changeset. This produced an error when attempting to create a subdirectory during the tests.
This adds the `tests/phpunit/data/filesystem/archive.zip` file.
