Bug 1224207 - Part 6. Move GetCSSPxToDevPxMatrix to nsSVGUtils. r=mstange

Browse Source 
To use GetCSSPxToDevPxMatrix in nsFilterInstance, pull this untility function down
to nsSVGUtils; Otherwise, we have to include nsSVGIntegrationUtils header in
nsFilterIntance, which is ok but not good I think.
