8296330: Tests: Add layout container snapping tests

[Maran23]

While checking https://bugs.openjdk.org/browse/JDK-8295078 I found much more layout container which do not snap their children correctly.

The goal of this PR is to add snapping tests for all layout container.
After that we can create issues for all broken layout container, fix them and comment in the corresponding line.
