Summary: At least one test requires the physical size to be set.

Test Plan:
Lock screen screen edges test is passing again. Without the change the corner
offset in the ScreenEdges class is not calculated correctly via the
physicalDpiX() and physicalDpiY() values of an auxilliary QWidget.

Summary:
With the new Output class we can set the gamma directly here. This is also
a stepping stone to adjust individual output gamma adjustment later on.

This means any future backend, which aims to support the color correction
frontend needs to use the Output class.

Test Plan: Night Color test still passes.

Summary:
Let VirtualOutput be a child class of the new generic class Output.
This allows code sharing and a very similar behavior of the Virtual backend
in comparision to the Drm backend.

Test Plan:
Autotests succesful with two exceptions: The decoration input test fails on
testDoubleTap, row topLeft. This is to be expected because now the
ScreenEdgeInputFilter captures the event at position (0,0) before the
DecorationEventFilter can capture it. The autotest was adapted to take this
special case into account.

Also the lockscreen test fails, because the virtual output is currently missing
the physical size yet.

Lift high-level properties into new Screens child class for platform plugins

Summary:
In order to separate high-level properties of individual outputs from
hardware-specific ones and access these, introduce a new generic class Output.

Also make the DrmOutput class directly a child class of this generic class.

The long-term goal is to get rid of the Screens global object on Wayland and
instead directly work with Output objects on compositing level.

This should enable us long-term to do direct scanout to hardware planes, what
I predict needs this generic output representation at one point.

Test Plan: Manually.

Summary:
While BuiltInEffects has effectData() function, many functions repeat
s_effectData.at(index(effect)), which is what effectData() is doing.

By using effectData(), we'll get rid of those repetitions and maybe make
easier transition to other underlying data structure that stores metadata
for builtin effects.

Test Plan: Compiles, all enabled builtin effects are loaded and working.

Summary:
The Dim Inactive effect sees the world a little bit differently.
m_activeWindow is currently active window that can be dimmed later on.
In most cases, it's the same as effects->activeWindow(). In rare cases,
it can be nullptr, even when effects->activeWindow() is not equal to nullptr
(e.g. when active window is a context menu popup).

canDimWindow is a helper that returns true if a given window should be
dimmed, otherwise it returns false. It has one special case: if a given
window is equal to m_activeWindow, return false. I.e. don't dim active
windows.

Currently, if user changes config of this effect, active window becomes
dimmed.

The reason for that is we hit that special case when deciding whether
effects->activeWindow() should be m_activeWindow.

This change addresses that problem by resetting m_activeWindow so we
don't hit that special case.

Test Plan:
* Opened KCM of this effect;
* Changed strength;
* (the KCM window stayed bright after I clicked "Apply" button).

(everything else works as expected)

Summary:
The Dim Inactive effect was rewritten mostly to fix most of issues with
it, e.g. after leaving a full screen effect(e.g. Desktop Grid) windows
sometimes are not dimmed back, or when a window becomes inactive there
is no smooth transition, etc.

{F5956124}
//Before: the window is not smoothly dimmed.//

{F5956127}
//After: the window is smoothly dimmed.//

In combination with an effect that animates the disappearing of windows,
e.g. Glide, the rewritten Dim Inactive effect doesn't "flash" windows.
If an active window has been closed, it will stay bright. If an inactive
window has been closed, it will stay dimmed.

Among other changes, the KCM has been re-designed to follow common KCM
design in Plasma:

{F5956128, layout=center, size=full}

The way the rewritten Dim Inactive effect handles flashing/flickering problem can be
reused in the Dialog Parent effect.

### Demo

{F5959885}
//Before: dimming of a window group.//

{F5959886}
//After: Dimming of a window group.//
