freedreno/ir3: don't treat all inputs/outputs as vec4
This was a hold-over from the early TGSI days, and mostly not needed
with NIR. This avoids burning an entire 4 consecutive scalar regs
for vec3 outputs, for example. Which fixes a few places that we were
doing worse that we should on register usage.
