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.
