SF: Pass owning Layer when creating LayerFE

This is a quick patch for ARC so that the LayerFE's know what Layer they
correspond to. A recently reverted change to remove
legacyFrontEndEnabled broke ARC targets as the new code created
LayerFE's that didn't know the corresponding Layer, and caused other
startup failures as a result.

Bug: 337894453
Test: Play Store is usable on Chromebooks
Test: atest libsurfaceflinger_unittest
