[video_player] Fix layout issue caused by Transform.rotate not affecting space calculation. (flutter#8685)

This pull request resolves [#159724](flutter/flutter#159724).
The issue occurs because `Transform.rotate` is used when `rotation` is not 0. Since `Transform` does not affect space calculations, this leads to the issues.

This is related to [flutter#7846](flutter#7846).
