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.
