Vulkan: Cleanup device feature query and enabling All device extension features and properties queries are now performed in a single call for each (i.e. one for features, one for properties), with all the extension structs chained. Then based on which feature is present (not just whether the extension is supported), the extensions and features are enabled. In the process, it fixes the following issues: - If VK_EXT_vertex_attribute_divisor is present, but the necessary vertexAttributeInstanceRateDivisor feature is not supported, that feature is not enabled and the emulation path is taken. Incidentally, this also fixes an issue with renderdoc that refuses to replay captures on such devices. - If VK_EXT_transform_feedback is present, but the necessary transformFeedback feature is not supported, similarly that feature is not enabled and the emulation path is taken.
