gallium: add bitmap/drawpixels texcoord bias support
The state tracker will call pipe->get_paramf(PIPE_CAP_BITMAP_TEXCOORD_BIAS)
to get a bias factor for adjusting the texcoords used in bitmap/drawpixels.
This allows us to compensate for small differences in rasterization from
one device to another.
