Fix up maximumCSSSampleId, and also add a presubmit check.

The presubmit check scans the whole UseCounter.cpp file upon a change, as it
needs to potentially read lines that were not modified. For example, if the largest
bucket id is commented out, the maximumCSSSampleId still needs to stay the
same.

Move SVGElement::finishParsingChildren to SVGSVGElement

Move SVGElement::finishParsingChildren to SVGSVGElement since it only performs actions on <svg>. This means we have to do one less check and SVG elements other than <svg> will have faster execution for finishParsingChildren.
