FPU: Remove FPU Compare Hack

FULL clamping mode fix games where hack was used, so is no longer required.
This commit remove hack, adjust GameDB according to that change, and rename fpuFloat4 function to fpuFloat3.
Last change is because fpuFloat3 was just wrapper for fpuFloat4 with added check for compare hack.
Additionally fpuFloat2 was only function that called fpuFloat4 directly, so that one call was changed to fpuFloat3 to respect previous changes.
