For GPU like ARM mali Utgard EGL/GLX_EXT_buffer_age will make performace worse. But mesa has no way to disable it.
This patch series make driver be able to disable it and add a gallium pipe cap for gallium driver usage. Due to currently only out of tree lima driver need it, and not sure if this is the right way to disable it, so I send this RFC before lima be able to upstream.
