Fixes #20717.
CdkTablecan receive an identity change from its iterable differ while a customtrackBykeeps the same row identity. Previously,renderRows()only updated the row data context, so a changedwhenresult left the old row template rendered.This change records the row definition used by each embedded row view and replaces only a view whose definition changes. Rows whose definitions are unchanged keep their existing DOM nodes.
