mesa: Allow querying the system FBO in GetFramebufferAttachmentParameteriv
If the default framebuffer is bound to <target>, then <attachment> must be one of FRONT_LEFT, FRONT_RIGHT, BACK_LEFT, BACK_RIGHT, AUXi, DEPTH_BUFFER, or STENCIL_BUFFER, identifying a color buffer, the depth buffer, or the stencil buffer, and <pname> may be FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE or FRAMEBUFFER_ATTACHMENT_OBJECT_NAME. as well as these <pname> values FRAMEBUFFER_ATTACHMENT_RED_SIZE, FRAMEBUFFER_ATTACHMENT_GREEN_SIZE, FRAMEBUFFER_ATTACHMENT_BLUE_SIZE, FRAMEBUFFER_ATTACHMENT_ALPHA_SIZE, FRAMEBUFFER_ATTACHMENT_DEPTH_SIZE, FRAMEBUFFER_ATTACHMENT_STENCIL_SIZE, FRAMEBUFFER_ATTACHMENT_COMPONENT_TYPE, or FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING. https://bugs.freedesktop.org/show_bug.cgi?id=28551
