Subject: [PATCH] rhi: vulkan: Enable feature for line polygon mode

Turns out there is a fillModeNonSolid in VkPhysicalDeviceFeatures,
so to be true to the spec we need to enable that when setting the
polygonMode in a QRhiGraphicsPipeline to something other than the
default Fill. This way the validation layer won't bark at us.
