layout: Avoid ClipId, ExternalScrollId and ScrollTreeNodeId references (#39372)

Browse source 
Changes function signatures to accept `ClipId`, `ExternalScrollId` and
`ScrollTreeNodeId` instead of `&ClipId`, `&ExternalScrollId` and
`&ScrollTreeNodeId`. This avoids several `&` and `*`.

Testing: not needed, no behavior change.
