Visual Studio 9 2008

Removed. This once generated Visual Studio 9 2008 project files, but the generator has been removed since CMake 3.30. It is still possible to build with VS 9 2008 tools using the Visual Studio 14 2015 generator (or above, and with VS 10 2010 also installed) with CMAKE_GENERATOR_TOOLSET set to v90, or by using the NMake Makefiles generator.
