StaticHashSetNodeList is unnecessary

Reviewed by Antonio Gomes.

Source/WebCore: 

Moved Document::nodesFromRect into Internals::nodesFromRect per
https://chromium.googlesource.com/chromium/blink/+/78207c5c34383fbb807bb9347deb67168f09bb04.

Also made TouchAdjustment functions use HashListSet directly instead of wrapping it inside
a StaticHashSetNodeList since there was no need to use the latter.

With these two changes, I deleted StaticHashSetNodeList.
