Automatic update from web-platform-tests [Selection API] Add composed range endpoints We update Range API to support composed range. Previously, when setting the start/end range endpoints, if they are in different node trees, they will be collapsed. Now, if start/end are in different node trees, but same document, composed_range_ will be set to track those cross shadow tree endpoints. We update Selection::GetComposedRanges to use composed start and end to create a composed StaticRange. We fix Selection::GetComposedRanges to use IsShadowIncludingInclusiveAncestorOf for Rescoping and add a test.
