SWC files don't work when zlib extension is built as shared

Description

The following code:

./buildconf
./configure --with-zlib=shared
make
./sapi/cli/php run-tests.php -d extension_dir=modules ext/standard/tests/image/getimagesize_swc.phpt

Resulted in this output:

test skipped

But I expected this output instead:

test passed

To have SWC files (even though they are obsolete), the zlib extension needs to be built statically with PHP. This prevents packages to build a shared zlib extension. As there is now a new API and image types can be dynamically registered from extensions, this can be probably resolved differently as done in the previous pull requests.

使用提供的构建命令和 ext/standard/tests/image/getimagesize_swc.phpt 重现该问题。参考所提到的 pull request 和错误报告，跟踪在共享 zlib 时 SWC 图像支持是如何注册的。无需静态构建 zlib 且测试通过，即视为完成。
