[clang] [Clang] Change Attribute plugin to link clang-cpp like other examples (PR #109319)

[Thomas Fransham via cfe-commits]

https://github.com/fsfod created https://github.com/llvm/llvm-project/pull/109319

Change the Attribute example plugin to use clang_target_link_libraries instead of target_link_libraries so libclang-cpp is linked when the CLANG_LINK_CLANG_DYLIB CMake option is used. 
This change will allow building the plugin on windows when building llvm and clang as a shared library with explicit visibility macros enabled.
