input: add support for Pickup and Hangup keys

Draft as untested as of yet.

The context: https://discuss.kde.org/t/fn-keys-not-working-on-wayland-they-work-on-x11/36536

https://doc.qt.io/qt-6/qt.html#Key-enum does no seem to have something for:

#define XF86XK_NotificationCenter       _EVDEVK(0x1bc)  /* v5.10   KEY_NOTIFICATION_CENTER */

xkbcommon ref: https://github.com/xkbcommon/libxkbcommon/blob/master/include/xkbcommon/xkbcommon-keysyms.h

This requires a matching patch to Qt https://github.com/qt/qtbase/blob/dev/src/gui/platform/unix/qxkbcommon.cpp#L250 similar to https://github.com/qt/qtbase/commit/4396c96f1e77869631b5067c5ef3be61305899f5

DIKS_CALL (https://github.com/DirectFB/directfb/blob/master/include/directfb_keyboard.h) can be use for PhonePickup, I think.
