react: Fix wrong type for e.currentTarget

[ypresto]

Many component type definitions uses React.Component subclass or {} for T of HTMLProps<T> or HTMLAttributes<T>, etc.
But it is used for e.currentTarget passed to event handlers and it (T) should be HTMLElement.

(This PR contains #14618 because it will conflict on below line:)

-    interface SVGAttributes<T> extends HTMLAttributes<T> {
+    interface SVGAttributes<T extends SVGElement> extends DOMAttributes<T> {
