[Shadow] Performance tests of distribution for changing select attribute
https://bugs.webkit.org/show_bug.cgi?id=103611
Reviewed by Hajime Morita.
We would like to measure ShadowDOM performance and compare it to the similar functional HTML without using ShadowDOM.
In this patch, we add a case when select attribute of HTMLContentElement is changed.
* ShadowDOM/ChangingSelect.html: Added.
* ShadowDOM/ChangingSelectWithoutShadow.html: Added.
