LOG: [Clang] Include the clang-shlib CMake project when building for MSVC (#109457)

Enable building clang-cpp shared library for windows when building with
explicit visibility macros enabled and LLVM is built as a shared
library(LLVM_BUILD_LLVM_DYLIB_VIS).
This is part of the effort to support for enabling plugins on windows by
adding better support for building LLVM and Clang as a DLL.
