ParseAttribute ideally would be const (see bug 1829138), but the SVG and SMIL code is rather messy. Still, now that BeforeSetAttr can't really fail, swapping the order of ParseAttribute and BeforeSetAttr shouldn't really change behavior. Sorry for the extra `virtual` keyword removal and such. I had to do this one by hand unlike the dependent bugs, and I went a bit drive-by, lmk if you want me to split those changes. Differential Revision: https://phabricator.services.mozilla.com/D176086
