Sebastian Keller b28a6e50a0 tests: Add test for maintaining constraints after client resizes
This test ensures that windows that were resized such that they extend
beyond the screen will be moved to be fully on the screen (if possible).

This has been working on X11 since forever, but on Wayland only since
the last commit.

# Tests that constraints are applied after a client initiated resize
# 1. Create a window that does not extend beyond the screen
# 2. Move it to a known position
# 3. Resize such that the following resize will extend beyond the screen
# 4. Check that the window was moved to the position that would allow it to fit on the screen
