lang/php*-extensions: Fix version numbers and Makefile ordering

- Update pkg-descr files to show correct PHP version (was 8.0 for all)
- Update COMMENT in Makefiles to include correct version branch
- Fix Makefile variable ordering (IGNORE_WITH_PHP before PHP_VER)
- Fix incomplete IGNORE_WITH_PHP entries to include all other PHP versions
- Apply portfmt formatting

While here, ensure all ports pass portclippy validation.
