dom: Firing "click" event as synthetic pointer event (#36274)

According to specification

https://html.spec.whatwg.org/multipage/webappapis.html#fire-a-click-event
"Firing a click event at target means firing a synthetic pointer event
named click at target"

So need to replace synthetic mouse event with "click" type to pointer
event.

https://w3c.github.io/pointerevents/#the-click-auxclick-and-contextmenu-events
https://www.w3.org/TR/uievents/#event-type-click

Firing "click" event could be triggered from script or by UA:
- element.click()
(https://html.spec.whatwg.org/multipage/interaction.html#dom-click)
- form implicit submission
(https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#implicit-submission)
- keyboard activation (space)
