Disable building of shared libraries with LLVM and MinGW so that remaining __declspec macros needed for the functional libraries built by MSVC can be used without triggering errors in LLVM and MinGW builds. For Windows only install the default_library type to avoid confusion. Windows builds cannot build both shared and static in a single pass so install only the functional variant.
