VideoCommon: Use integer arithmetic instead of floating point arithmetic when dealing with EFB scales.

Browse Source 
Should fix problems caused by EFB scales other than Native (excluding fractional!). Test whether this fixes games which work fine with native EFB resolution but show glitches with higher internal resolutions.

Also fixed numerous warnings.
