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.
