Remove beginLayoutLw and redundant logic about layout

This CL makes every window always ready to layout. DisplayFrames and
InsetsState will be always up-to-date so that we don't need to update
them in beginLayoutLw anymore.

This CL also removes PRIVATE_FLAG_PRESERVE_GEOMETRY which is not used by
anyone.

This can be a step to make the client compute its window frame locally.
