Upgrade SwiftShader solution and projects to Visual Studio 2017.
Chrome now uses Visual Studio 2017 as the default compiler on Windows.
To ensure we maintain compatibility during standalone development, we
should use VS2017 for SwiftShader as well. The 'Community' edition of
Visual Studio 2017 is freely available.
