Summary:
To have touch events working we need to do memory layout changes on the
xcb events. This is fine for identifying the touch events which should
trigger the screen edge. But when passed on to Qt to have QtQuick windows
(e.g. Alt+Tab) handle the touch events, this results in a problem:
Qt itself does also the memory movement and then the movement is double
and touch events break.
To prevent this problem an RAII class is added which moves the memory in
the ctor and moves it back in the dtor. So during KWin's processing it
has the right memory layout and later on in Qt's processing it has the
proper "wrong" layout which Qt can fix again.
Test Plan: Touch events in Alt+Tab work

Summary:
Grabbing the touch events seems to cause issues. It seems to also grab
pointer events from touchpad and breaks touch input on other events.
Also testing shows that we don't need it and get touch ownership events
for our screenedge windows reported.

Summary:
This change extends the XInputEventFilter to also listen for all touch
events on the root window.
The touch points are passed to the new gesture recognizer in screenedges.
Please note that I'm not using X11 and have hardly tested this change in
real world. To our X11 users with touch screen support: please test!
Test Plan: Can activate and deactivate the screenedge.

Summary:
The functionality regarding triggering modifier only shortcuts is moved
out of Xkb - where it doesn't belong to - and is turned into an input
event spy listening for the changes it is interested in. Previously
the state got queried by asking e.g. for the pressed buttons, now it's
tracked directly.
The X11 side needs a larger change due to that as now pushing the events
into Xkb does not trigger modifier only shortcuts any more. Instead the
"normal" way through the platform API needs to be used which triggers the
processing of filters and spies.
The problem here is that our redirections only process events if they are
inited and that only happens on Wayland. We cannot call init on them as
that would create all the Wayland filters and spies and processing would
probably break. As an intermediate solution the spies are now processed
and there we know that it won't matter. A future solution would be to
remove the init checks completely and just send through both filters and
spies and ensure that on X11 only the supported ones are loaded.

Summary:
And finally nothing inside libkwineffects, libkwinglutils,
libkwinxrenderutils and kwineffect and kwin core uses KWin::display.
We are finally XLib free!
This change drops KWin::display and removes the include to QX11Info from
kwinglobals.h. And the libraries no longer need to link X11Extras. Due
to that removal a few seeming unrelated changes are required to add the
include where needed and linkage to X11Extras.
The biggest change is to x11 platform plugin which still needs the
display and caches it in the Platform and passes it to various places in
a way that the code doesn't need to be adjusted.

Summary:
The modifier-only-shortcuts break as soon as KWin grabs the keyboard
(e.g. alt+tab, present windows, etc.). The investigation shows that in
that case KWin does not get any raw key events any more and thus gets
confused about the state of the hold modifiers. E.g. alt+tab has the
alt key pressed, but we miss the release as the keyboard is grabbed.
This change addresses the problem by installing an additional event
filter for key press and release event which only filters for key events
on the root window. That way we can be sure that it only operates when
KWin grabbed the keyboard on the root window.
Note: the problem only exists when grabbing on the root window. If the
grab is on another window (e.g. moving a window) we still do get all
events.
The problem also seems to not happen if another application grabbed
keys on the root window. E.g. for key combinations grabbed by
kglobalaccel the correct sequence of key press/release as raw events
are reported. Also while the screen is locked the evemts are reported
and kscreenlocker grabs the keyboard on the root window.
Test Plan:
Used Alt+Tab and Present Windows and tried to activate launcher
afterwards.

Summary:
The raw pointer button events intercepted in the XInput2 input filter
get sent through the Platform to the PointerInputRedirection. This
makes the PointerInputRedirection track the pointer button state and
emit the signals for button changed and axis changed.
These signals are used by the modifier-only shortcut detection to
determine whether the shortcut should trigger.
On X11 the "normal" input handling doesn't use the InputRedirection
and the emitted signals are not consumed by anything else. As
PointerInputRedirection is not inited the events are not forwarded
to the input filter, thus won't be processed by other parts and
won't interfere with the normal event processing on X11.
Given that it also doesn't matter that the input filter does not
apply the left-handed setting. The internal tracking will have a
wrong mouse button, but nothing is going to do decisions based on
the value of the pressed mouse button. For the moment all we are
interested in is that a button is pressed.
Test Plan:
Pressed meta, clicked, scrolled, released meta: launcher
did not open. Pressed meta, released meta: launcher opened

BUG: 367730
At the same time the xinput2 integration is split out of X11Cursor
and made a standalone part of the platform plugin. XInput integration
is nowadays not only used by the cursor position polling, but also
for modifier only shortcuts.
By splitting it out the modifier shortcuts start to work also when
one doesn't have anything requesting a mouse position polling.
This also simplifies the conditional builds: xinput integration is
only included if we have support for it at compile time without having
to have many ifdefs in the cursor implementation. For the inclusion of
cursor in the kcmkwin this also removes all the ifdefs.
The key events are only requested if we have xinput 2.1. Otherwise we
would not get all raw events if the input device gets grabbed.
