Coordinate configuration changes and window frame size.

Previously, it was possible for the view hierarchy to be measured,
laid out, and drawn around a window frame size that did not match
the current configuration. This stems from new configurations not
always propagating back from WindowSession#relayout, which is
called from ViewRootImpl.

This changelist makes WindowManagerService#relayoutWindow always
return the latest configuration. It also adds rotation to the
configuration.

Fixes: 32839232
Test: go/wm-smoke
Test: Open Camera while rotating phone to landscape. Added
      temporary logs to detect inconsistencies between measurements
      and reported rotation on draw.
