Partly revert the fix from webkit.org/b/198576 (REGRESSION (r243121): Load event should not be fired while animating the 'externalResourcesRequired' attribute), that landed in https://commits.webkit.org/212621@main. First of all, externalResourcesRequired support is gone from WebKit, therefore SMIL animations of that property are no longer possible: the workaround is obsolete. More importantly, the applied workaround is harmful for SVGTransformList animations, which go through the same SVGAnimatedPropertyAnimator code paths to apply changes, when <animateTransform> animations are active. @said: I hope the ChangeLog is sufficient :-) [I wanted to mark this as depends-on 198576, but I have no rights to do so]

It's a draft PR, still need to update baseline / eventually add a new test (broke this out of a chain of commits, waiting for my builds to catch up... :-)
