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.
