Make the total padding between windows equal to the padding against the
screen borders by applying just half of it on the common borders.
Adjust tests accordingly.

FIXED-IN: 5.27.6
Use input device specific apis to change the position of the cursor. The
main reason to do so is to break the assumption that Cursor position is
the same as pointer position, which I would like to rely on later to
merge tablet and pointer cursors.
* Allow to do quick tiling to custom tile geometries, windows will be snapped to tiles when dragged with the shift modifier pressed.
* Tile geometries are screen specific.
* The global shortcut Meta+T will trigger a fullscreen configuration ui as a QML effect for the tiles which allows to add, remove and resize tiles
* UI and behavior is a bit similar to the Windows Fancy Zones addon: https://docs.microsoft.com/en-us/windows/powertoys/fancyzones
* Its main scope is to help the workflow with very big monitors, especially ultra wide ones, where most application don't make sense maximized to the full screen (eventually also support games to be full screened to a given tile instead of the whole screen)
* it should get also some bindings for scripting, as its ain goal is not to replicate other popular tiling window managers, but should give the popular kwin tiling scripts to have a more robust infrastructure
* it will eventually get support for a set of predefined layouts, but this is for a second phase
