Add coverage for depth bias with polygon topologies and fill modes
In these test we are applying the depth bias by using
depthBiasConstantFactor. Polygon topologies with fill, line and point
polygon modes are tested.
Components: Vulkan
VK-GL-CTS Issue: 3055
New tests: dEQP-VK.draw.renderpass.depth_bias.depth_bias_*
Change-Id: I5cb5a1c8ee13fa0f6c56edaf21eda4e19b6d144c
