Disable support for 3D graphics APIs

Prevent web pages from accessing the graphics processing unit (GPU). Specifically, web pages can't access the WebGL API and plug-ins can't use the Pepper 3D API. If you don't configure or disable this policy, it potentially allows web pages to use the WebGL API and plug-ins to use the Pepper 3D API. Microsoft Edge might, by default, still require command line arguments to be passed in order to use these APIs. If 'HardwareAccelerationModeEnabled' (Use graphics acceleration when available) policy is set to false, the setting for 'Disable3DAPIs' policy is ignored - it's the equivalent of setting 'Disable3DAPIs' policy to true.
