cmake: correctly handle linker flags for static libs

curl CMake was setting the the EXE flags for static libraries which made
the /manifest:no flag ended up when linking the static library, which is
not a valid flag for lib.exe or llvm-lib.exe and caused llvm-lib to exit
with an error.

The better way to handle this is to make sure that we pass the correct
linker flags to CMAKE_STATIC_LINKER_FLAGS instead.

cmake: don't pass -fvisibility=hidden to clang-cl on Windows

When using clang-cl on windows -fvisibility=hidden is not an known
argument. Instead it behaves exactly like MSVC in this case. So let's
make sure we take that path.

In CMake clang-cl sets both CMAKE_C_COMPILER_ID=clang and MSVC get's
defined since clang-cl is basically a MSVC emulator. So guarding like we
do in this patch seems logical.
