Let activities of Telecomm opt out edge-to-edge

This is a temporary solution to prevent the layout issue while
enabling the feature flag of the edge-to-edge enforcement.

We still need to make activity handle insets properly later.

Fix: 332663986
Bug: 309578419
Flag: com.android.window.flags.enforce_edge_to_edge
Test: Open settings of Phone, and open each sub-settings. Make sure
      there is no critical element obscured by the action bar.
