Summary:
Maximized clients weren't considered as resizeable when quick tiling was
added. Therefore, a special case was added in Client::setQuickTileMode().
However, that special case didn't take into account that a fullscreen
client can be also maximized. Clearly, we don't want users quick tile
fullscreen clients.
BUG: 411028
FIXED-IN: 5.17.0
Test Plan: No longer able to quick tile maximized fullscreen window of Konsole.

Secondly deleting the adaptor doesn't really make sense, you'd still
leave the object valid, only have it broken. Docs of

Summary:
In order to pick the next client to activate we traverse the stacking
order from bottom to top and assign to each client a score. The client
with the best score will be activated next. Function that assigns score
bases its decisions purely on geometry. This may backfire if there are
couple maximized or fullscreen clients on the screen - we'll activate
the bottom-most client.
This change toggles direction we traverse the stacking order. If there
are several clients with an identical score, then prefer the top-most
client, the one that the user most likely sees at the moment.

Summary:
Any call made to a virtual method in constructor/destructor of a base
class won't go to a derived class because the base class may access
uninitialized or destroyed resources.
For example, let's consider the following two classes
class Base {
public:
Base() { foo()->bar(); }
virtual ~Base() { foo()->bar(); }
virtual Foo* foo() const { return nullptr; }
};
class Derived : public Base {
public:
Derived() : mFoo(new Foo) {}
~Derived() override { delete mFoo; }
Foo* foo() const override { return mFoo; }
private:
Foo* mFoo;
};
When an instance of Derived class is created, constructors will run in
the following order:
Base()
Derived()
It's not safe to dispatch foo() method call to Derived class because
constructor of Derived hasn't initialized yet mFoo.
Same story with destructors, they'll run in the following order:
~Derived()
~Base()
It's not safe to dispatch foo() method call in the destructor of Base
class to Derived class because mFoo was deleted.
So, what does that weird C++ behavior has something to do with KWin? Well,
recently Compositor class was split into two classes - WaylandCompositor,
and X11Compositor. Some functionality from X11 doesn't make sense on
Wayland. Therefore methods that implement that stuff were "purified," i.e.
they became pure virtual methods. Unfortunately, when Compositor tears
down it may call pure virtual methods on itself. Given that those calls
cannot be dispatched to X11Compositor or WaylandCompositor, the only
choice that C++ runtime has is to throw an exception.
The fix for this very delicate problem is very simple - do not call virtual
methods from constructors and the destructor. Avoid doing that if you can!
This change moves Compositor::updateClientCompositeBlocking to X11Compositor
so it longer has to be a virtual method. Also, it kind of doesn't make sense
to keep it in base Compositor class because compositing can be blocked only
on X11.
BUG: 411049
Test Plan: KWin no longer crashes when running kwin_x11 --replace command.

This removes the alternative code path used before in these backends, what
simplifies the code and is also a prerequisite to removing the Screens global
