Always send configuration to client from resize and relayout.

Previously, the server side would omit reporting new configurations
during resize and relayout if the current configuration matched the
last reported. However, if the last reported came through a resize,
the client side handling would be enqueued as a Handler message. This
leads to the possibility of the client getting a new window frame but
not a new configuration where this is synchronously handled, such as
ViewRootImpl::performTraversals.

To address this issue, we now always send the current configuration
from the server to the client. The client then identifies changes
against its own record of last reported configuration and updates as
appropriate.

This changelist also adds a call to force window relayout during
updateConfiguration, as it's possible this is called after
performTraversals is called or resize is handled, leading to a stale
window frame.

Bug: 24671393
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.
