Fix build 2404

[daizhirui]

Fixed a build issue with Ubuntu 24.04 when cmake is configured with the following arguments:

-DBUILD_SHARED_LIBS=ON
-DUSE_SYSTEM_EIGEN3=ON
-DUSE_SYSTEM_FMT=ON
-DUSE_SYSTEM_GOOGLETEST=ON
-DUSE_SYSTEM_JSONCPP=ON
-DUSE_SYSTEM_NANOFLANN=ON
-DUSE_SYSTEM_PYBIND11=ON
-DUSE_SYSTEM_QHULLCPP=ON
-DGLIBCXX_USE_CXX11_ABI=ON
-DBUILD_EXAMPLES=OFF
-DBUILD_UNIT_TESTS=OFF
-DBUILD_BENCHMARKS=OFF

The compilor complains that std::shared_ptr is not defined in cpp/open3d/visualization/rendering/Renderer.h.
