Options length setter should process custom elements reactions

Options length setter should process custom elements reactions

Unlike HTMLCollections, the HTMLOptionsCollection length attribute is
writable and it can remove elements from the DOM on truncation, which
should trigger custom element reactions. Add the metadata to do that.

This means Blink is now passing web-platform-tests'
custom-elements/reactions/HTMLOptionsCollection.html tests.
