Summary:
Unfortunately Xkb does not emit a signal when the keyboard layout
changes. Due to that we need to manually check in KeyboardLayout after
each action which could change the layout whether the layout changed.
This was not yet done for the case when the layout got changed through
the DBus interface. Resulting in the DBus signal not emitted.
This change addresses the issue by invoking the check for change after
changing the keyboard layout.

Summary:
This change introduces a new class KeyboardLayoutDBusInterface which
implements the same DBus interface as the keyboard kded module.
Thus components which interact with the keyboard kded through dbus start
to also work on Wayland.
Together with D4322 this should result in keyboard layout being available
on the lock screen.

Test Plan:
Tested with qdbusviewer: switching layout works, signal on
change gets emitted.

Summary:
Our keyboard layout kcm allows to set a global shortcut to switch to a
specific keyboard layout. So far KWin/Wayland did not support those
shortcuts, only the switch to next layout shortcut was supported.
This change introduces support for custom layout shortcuts. For that
we iterate over all available layouts and check whether a shortcut is
registered. If that is the case a QAction is created and passed to
KGlobalAccel.
As the triggering code is similar to the menu, the switchLayout lambda
is split out into a dedicated method and translating the layouts is
extracted into a method.

Summary:
On X11 the SNI for keyboard layout is provided by the keyboard kded.
On Wayland that kded has no real access to the layouts and cannot
properly implement switching. Given that it's better to integrate the
SNI directly in KWin.
The implementation of the SNI is largly based on the existing SNI from
plasma-desktop/kcms/keyboard. The implementation so far supports:
* Switching to next layout on toggle
* Presenting all layouts in a context menu
* Switching to a specific layout through the context menu
* Opening the keyboard layout configuration module
* scroll on SNI to switch layout
* config option whether to show the SNI
Not yet supported are:
* flags and/or short text for the layouts
The last point needs more explanation. On X11 the layout name is
something like "de" or "us". This can be directly mapped to a flag and
can be added as a short note.
Xkbcommon does not provide this information directly. Instead it provides
us the full name of the layout, e.g. "German" or "English (us)". There is
no way in the API to go from "German" to "de".
Instead we need to parse the evdev.xml file to gather all information
about layouts. This is already done in the keyboard kcm to configure
layouts. The implementation needs to be split out into a small helper
library.

Summary:
So far the implementation of keyboard layout handling was split between
KeyboardInputRedirection and Xkb. KeyboardInputRedirection registered
the global shortcut and did the handling for layout switch and config
changes. Xkb did the notification on layout change.
Layout changes can nowadays be detected through an InputEventSpy. It
can only happen after a key change or an explicit layout switch. Thus
it does not need to be in Xkb anymore which allows to reduce Xkb to
only care about the Xkb keymap and state tracking.
This change introduces a new class KeyboardLayout which is an
InputEventSpy and takes over the task of the layout change notification
from Xkb and the layout management from KeyboardInputRedirection. Thus
everything related to management of keyboard layout is together in one
class.
This allows in future to add unit test to it (requires further cleanup
of Xkb to be able to use it and drop the InputRedirection dependency) and
opens the possibility to also take over keyboard layout management on X11
for the Plasma desktop.
