Combine docs for selection events under GlobalEventHandlers

[Elchi3]

Another test for GlobalEventHandlers.

WebIDL:

partial interface mixin GlobalEventHandlers {
  attribute EventHandler onselectstart;
  attribute EventHandler onselectionchange;
};

Document includes GlobalEventHandlers
Window includes GlobalEventHandlers
HTMLElement includes GlobalEventHandlers
MathMLElement includes GlobalEventHandlers
SVGElement includes GlobalEventHandlers

Before this PR, there were these 6 pages:

• Web/API/GlobalEventHandlers/onselectionchange
• Web/API/GlobalEventHandlers/onselectstart
• Web/API/Document/selectionchange_event
• Web/API/Document/selectstart_event
• Web/API/HTMLInputElement/selectionchange_event
• Web/API/HTMLTextAreaElement/selectionchange_event

Now there are these 2 pages:

• Web/API/GlobalEventHandlers/selectionchange_event
• Web/API/GlobalEventHandlers/selectstart_event

Per https://w3c.github.io/selection-api/#selectionchange-event the "selectionchange" event can be fired at Document, HTMLInputElement and HTMLTextareaElement. I think it'd make sense to have these as 3 pages, and link them together. (I haven't tested if they're actually supported.)

Closing as folks went with a different solution. mdn/browser-compat-data#16029 (comment)
