mesa/formatquery: Added framebuffer renderability related queries

From the ARB_internalformat_query2 specification:

   "- FRAMEBUFFER_RENDERABLE: The support for rendering to the resource via
      framebuffer attachment is returned in <params>.

    - FRAMEBUFFER_RENDERABLE_LAYERED: The support for layered rendering to
      the resource via framebuffer attachment is returned in <params>.

    - FRAMEBUFFER_BLEND: The support for rendering to the resource
      via framebuffer attachment when blending is enabled is returned in
      <params>."

For all of them,
    "Possible values returned are FULL_SUPPORT, CAVEAT_SUPPORT, or NONE.
     If the resource is unsupported, NONE is returned."
