ESSL does not support `GL_ARB_post_depth_coverage`. There, we must use `GL_EXT_post_depth_coverage`. I've added this as a fallback for desktop as well. Note that `GL_EXT_post_depth_coverage` also requires the fragment shader to set `early_fragment_tests` explicitly, while `GL_ARB_post_depth_coverage` does not. It doesn't really matter either way, since `SPV_KHR_post_depth_coverage` *also* requires both execution modes to be explicitly set.
