gallium/draw: use correct rasterization state for wide/AA points/lines

When points or lines are decomposed into triangles, we need to be sure
to disable polygon culling, stippling, "un-filled" modes, etc.

This patch sets the rasterization state to disable those things prior to
drawing points/lines with triangles, then restores the previous state
afterward.

The new piglit point-no-line-cull test checks this problem & solution.
