  Add a framebuffer fetch implementation of PLS
  
  The framebuffer fetch implementation works by attaching PLS backing
  textures to the framebuffer, and then rewriting PLS uniforms as "inout"
  fragment variables. The compiler's existing machinery takes it from
  there and makes it work on GL and Vulkan, and soon Metal.
  
  EXT_shader_framebuffer_fetch is now the preferred backend for pixel
  local storage, but we also use EXT_shader_framebuffer_fetch_non_coherent
  if shader images can't be coherent. This is especially interesting for
  Vulkan, since noncoherent framebuffer fetch is possible without any
  extensions.
