Rendertarget attachments, texture and image changes (#358)
* Add multiple color outputs for fragment shaders * Add registers and gal enums * Use textures for framebuffers and split color and zeta framebuffers * Abstract texture and framebuffer targets as an image * Share images between framebuffers and textures * Unstub formats * Add some formats * Disable multiple attachments * Cache framebuffer attachments * Handle format types * Add some rendertarget formats * Code cleanup * Fixup half float types * Address feedback * Disable multiple attachments in shaders * Add A4B4G4R4 image format * Add reversed section for image enums
