  Vulkan: Don't close render pass on framebuffer fetch
  
  For applications that use framebuffer fetch in the same RP as
  non-fetch programs, we can save some extra RenderPasses by always
  creating our RP objects with input attachments enabled.  This works
  almost identically except for needing to use the images in a
  "GENERAL" layout instead of "COLOR_ATTACHMENT_OPTIMAL".  According
  to partners it is possible to achieve performance parity even with
  GENERAL layout.
  
  To remove any potential negative impacts of using the GENERAL layout,
  the context enters this always-framebuffer-fetch mode only and as soon
  as a framebuffer fetch program is created.  Applications that don't use
  framebuffer fetch are thus unaffected.
  
  This eliminates 20 render passes in the Genshin Impact trace (out of
  about 58).  On a Pixel 6 the resulting benchmark score speeds up by
  ~25%.  For Real Racing 3, the speed up is ~30%.
