Install the MinGW build of libclang

This restores the MinGW installation of libclang on Windows 7 and
installs the MSVC and MinGW builds in parallel on Windows 10. For
compatibility reasons the MSVC installation is done last, to ensure that
the older LLVM_INSTALL_DIR variable points to the MSVC installation. In
addition though we now get LLVM_INSTALL_DIR_MINGW and
LLVM_INSTALL_DIR_MSVC, which qt_find_clang.prf in qttools can use in the
future.
