[perf-test] Make query-selector-last.html more realistic

https://bugs.webkit.org/show_bug.cgi?id=88203

Reviewed by Ryosuke Niwa.

query-selector-last.html tests querySelector() for an element
that appears after 1000 div elements, all of which have the same
id and class. To test the performance of querySelector() under
a lot of ids and classes, we should make the ids and classes of
the 1000 elements different.

This patch degrades the performance of query-selector-last.html
by 3.6%.
