mesa: Additional FlipY applications
Instances where direction was determined based on
winsys or user fbo and should be determined based on
FlipY.
Key STATE_FB_WPOS_Y_TRANSFORM for of FlipY instead of
_mesa_is_user_fbo. This corrects gl_FragCoord usage
when applying GL_MESA_framebuffer_flip_y.
Fixes: ab05dd183cc ("i965: implement GL_MESA_framebuffer_flip_y [v3]")
