u_blitter: Fix out-dated draw_rectangle handler doc

Browse source 
Remove mention of UTIL_BLITTER_ATTRIB_COLOR and
UTIL_BLITTER_ATTRIB_TEXCOORD and add a few words about
UTIL_BLITTER_ATTRIB_XY and UTIL_BLITTER_ATTRIB_XYZW.

Fixes: 22ed1ba01a ("gallium/u_blitter: use draw_rectangle for all blits except cubemaps")
Fixes: ca09c173f6 ("gallium/u_blitter: remove UTIL_BLITTER_ATTRIB_COLOR, use a constant buffer")
