4e9456a857 [platforms/x11] Fix incorrect screen edge approaching with switch desktop on window move
Summary:
There is a regression in WindowBasedEdge::soStopApproaching. Due to
only operate when the edge activates for pointer it is possible that
the cursor polling stays active. Explaining the situation:

1. Activate switch desktop when moving window
2. Start moving a window
3. Move mouse into the approach geometry
-> doStartApproaching activates as we are moving a window
4. stop moving window
-> doStopApproaching early exits as the position does not activate for
   pointer any more - we are not moving a window
-> cursor polling is still connected and whenever mouse enters edge
   approaching is started

The analysis shows that the check whether activates for pointer is wrong
in the case of stop approaching. If the edge started to approach, we also
need to stop approaching.

This change addresses the problem by turning the check into whether the
connection for cursor position update is set.

This is the third bug fix to the X11 screen edge handling after
introducing touch screen edges. This needs more manual testing by
everybody in the Plasma team who is still using X11.

aa6c8f8116 Add support for activating screenedges through touch swipe gestures
Summary:
Each Edge creates a SwipeGesture for touch activation. The swipe needs to
be a single finger starting from the edge into the screen for at least
20 %. The SwipeGesture and GestureRecognizer is extended to support the
use cases of the touch screen edge swipe.

New features supported by the gesture system are:
 * minimum and maximum position
 * a minimum delta for the swipe
 * progress signal based on the minimum delta
 * starting a swipe with a start point

The Edge has the progress signal connected to its approach signal, thus
visual feedback is provided through the screen edge effect.

The screen edge system supports touch only for the edges (corners are
too difficult to activate on touch screens). At the moment the following
features are supported:
 * screen edge show/raise of windows (e.g. auto hidden panels)
 * trigger the configured action
 * trigger the configured callback function (e.g. script)

In future it might make sense to add a touch specific configuration
action to support different actions for screen edges activated by mouse
and touch.

BUG: 370323

Test Plan:
configured a screen edge and triggered through touch,
added an auto-hiding panel and triggered through touch

e73a86d420 Create screen edge through the Platform
Removes a diversion between X11 and Wayland. The base class Platform
creates an instance of class Edge with plugin implementations being
able to create a different type.

The X11StandalonePlugin does that and creates a WindowBasedEdge. For
this the implementation of WindowBasedEdge is moved from screenedges
into the plugin.

Unfortunately an ifdef is needed to make the screenedge test still
work as expected. This should be improved in future, e.g. have a good
way to load the platform plugin from the tests.
