constraints: Delay initial maximization until after reparenting is done

Merged Sebastian Keller requested to merge skeller/mutter:delay-ssd-maximization into main

For SSD windows the decoration window from the frames client might have a different maximization state than the client window and would end up restoring it once shown. Avoid this issue by waiting until all reparenting is done before applying the initial maximization (and minimization).

Closes: #2579 (closed)
