Fix histogram timer in BaseRenderingContext2D::drawImage
In our current implementation, the histogram timer in the above function
doesn't account for the time that spends on decoding the source image.
That part of time can be significant for some image sources like SVG.
This CL fixes the timer to include the image source decoding time.
