svga: Advertise SVGA3D_DEVCAP_MAX_POINT_SIZE.
Backends usually advertise a SVGA3D_DEVCAP_MAX_POINT_SIZE between 63 and 256, so an hardcoded max point size of 80 is often incorrect. This limitation does not apply for anti-aliased points (as they are done via draw module) but we still advertise the same limit for both, because all others pipe drivers do.
