st/mesa: report correct precision information for low/medium/high ints

When we have native integers, these have full precision. Whether they're
low/medium/high isn't piped through the TGSI yet, but eventually those
might have differing precisions. For now they're just 32-bit ints.

Fixes the following dEQP tests:


which expected highp ints to have full 32-bit precision, not the default
23-bit float precision.
