vulkan: Record pipeline flags in the render pass

vulkan: Record pipeline flags in the render pass

This records any rendering pipeline flags in the render pass.  This
provides much-needed information for the VK_KHR_fragment_shading_rate
and VK_EXT_fragment_density_map extensions as well as provides an
alternative to VkRenderingSelfDependencyInfoMESA which is based on
VK_EXT_attachment_feedback_loop_layout.

v2 (Connor): Name something more general
v3 (Faith): Also add the FSR flag
