  Reduce unsafeness in WebKit/WebProcess/WebPage/EventDispatcher.cpp
https://bugs.webkit.org/show_bug.cgi?id=291936

Reviewed by Abrar Rahman Protyasha and Wenson Hsieh.

As per https://github.com/WebKit/WebKit/wiki/Safer-CPP-Guidelines

* Source/WebKit/Shared/WebEvent.h:

As need to create a CheckedRef on a different thread, use
CanMakeThreadSafeCheckedPtr.

* Source/WebKit/WebProcess/WebPage/EventDispatcher.cpp:
(WebKit::EventDispatcher::internalWheelEvent):
(WebKit::EventDispatcher::dispatchWheelEventViaMainThread):

As it's unclear how WebWheelEvent is kept alive today, we copy it.
