  REGRESSION(257087 at main): WebHitTestResultData ctor should check the argument `imageHandle` is nullopt
https://bugs.webkit.org/show_bug.cgi?id=248512

Reviewed by Carlos Garcia Campos.

After 257087 at main added a new serializer for WebHitTestResultData,
WinCairo WK2 Release and Debug layout tests were crashing.

* Source/WebKit/Shared/WebHitTestResultData.cpp:
(WebKit::WebHitTestResultData::WebHitTestResultData):
Check the argument `imageHandle` isn't nullopt before dereferencing.
