ui: Add bidirectional navigation between flamegraph and Ahat views
Adds size columns (shallow, native, retained, reachable) across all Ahat views. Adds flamegraph-to-Ahat navigation and removes legacy reference table options from the flamegraph context menu. Introduces mapCol utility for adapting shared column definitions. Change-Id: I6b3f522f5d5a82822decf247ce9b672941fe086a
