shared library suffix returns `d.so` rather than just `.so` when using debug about class_loader

Looking a bit into this it seems that we need to build poco with the definition POCO_NO_SHARED_LIBRARY_DEBUG_SUFFIX
https://github.com/pocoproject/poco/blob/558c7ff45fe32ffed02736b9732b4a9d8044aa53/Foundation/include/Poco/Config.h#L177

They don't expose that definition through CMake AFAICT so right now I'm tempted to extend the existing windows hack to the other platforms.

class_loader/src/class_loader.cpp

Lines 59 to 65 in adcb526

	#if !defined(WIN32)
	return Poco::SharedLibrary::suffix();
	#else
	// Return just .dll , as Poco::SharedLibrary::suffix() will return d.dll in debug mode.
	// This isn't common for our usecase (instead debug libraries are placed in a `Debug` folder).
	return ".dll";
	#endif

The other option would be to host a modified version of Poco in the ros2 org and to compile it with that definition.

Maybe we should consider to support that use case rather than providing custom built packages to avoid the debug suffix?
