rhi: Enhance line width and point size support
...but this will vary between backends, or in some cases even between implementations of the same API. Point size is settable only via the vertex shader (gl_PointSize). It is silently ignored with D3D and HLSL. Line widths other than 1 are supported only on OpenGL and Vulkan. (but this is in fact deprecated with GL and optional with Vulkan) Add QRhi::Feature values for both. The line width is now settable on QRhiGraphicsPipeline. It is not a dynamic state since the static, per-pipeline width is good enough for most cases. (and the feature is not supported on half of the backends anyways so it will get limited use in practice).
