tests/shader_runner: Introduce a "tessellation-shader" cap.

Browse Source 
Similar to how we have the "geometry-shader" cap. In principle shader
model 5+ implies support for tessellation shaders, but the Vulkan,
OpenGL, and Metal runners are able to support most of shader model 5+
without the underlying GPU (or API) necessarily supporting tessellation
shaders.
