[DirectX][SPIRV] Enable barycentrics support

[inbelic]

Required for testing of SV_Barycentrics

Current status: No support, but it can be tested through regular buffer readback.

AC:

• Add query for the required feature support (D3D12_FEATURE_D3D12_OPTIONS3::BarycentricsSupported, VK_KHR_fragment_shader_barycentric)
• VK: Enable the extension and chain VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR into device creation
• Add lit feature for barycentrics capability detection
• Add testing of the semantic by reading back the semantic values at known pixel centers
• Add similar testing of noperspective variant
