mesa: Add support for querying GL_FRAGMENT_SHADER_DISCARDS_SAMPLES_EXT.
This can currently only give true as result since the only way you can expose EXT_shader_framebuffer_fetch right now is by flipping the MESA_shader_framebuffer_fetch bit, but that could potentially change in the future, see [1] for an explanation.
