Subject: [PATCH 22/40] Wayland client: use wl_keyboard to determine active

 state

Commit f497a5bb87270174b8e0106b7eca1992d44ff15d made QWaylandDisplay

use the xdgshell's active state for QWindow::isActive(), instead of

using wl_keyboard activate/deactivate events.

That seems to have been a misunderstanding, since xdgshell activation

is only supposed to be used to determine visual appearance, and there

is an explicit warning not to assume it means focus.

This commit reverts this logic back to listening to wl_keyboard.

It adds a fallback when there is no wl_keyboard available to handle

activated/deactivated events through xdg-shell, in order to fix

QTBUG-53702.

windowStates is handled so that we're not using the Xdg hint for

anything with QWindowSystemInterface::handleWindowStateChanged or

anything where we need to track only having one active.

We are still exposing it for decorations, which is the only reason to

use the Xdghint over keyboard focus - so you can keep the toplevel

active whilst you show a popup.

cherry-pick 40036a1b80e5234e6db7d5cbeff122aa7ee13e20
