Using WindowContext for listening to configuration changes

Pre-S: Continue to use config-changed broadcast for configuration changes
and display-changed event for rotation changes
S+: Use WindowContext#componentCallbacks for config and rotation changes, and
continue to use display listener for frame-rate changes

Bug: 179308296
Test: Manual and presubmit
