Summary:
This is an alternative solution to T8707 and in comparision to D13276 a less
drastic change to KWin's default behavior.
Instead of changing the border size default for all KDecoration plugins by
switching the default from border size Normal to None introduce new
functionality, which allows a KDecoration plugin to recommend a border size in
its metadata. By default KWin listens for these recommendations and sets the
border size accordingly.
If there is no metadata recommending a border size, KWin falls back to the
current setting of Normal sized borders.
A user is able to override the recommendations from the KCM, which has been
extended accordingly.
Test Plan: Manually with adjusted metadata of Breeze.

Summary:
In KDE 4, there was a very handy option to disable decoration tooltips.
Decoration tooltips were lost in transition to KDE Plasma 5, and so
the option.
Given that decoration tooltips were brought back to KDE Plasma 5, "Show
decoration button tooltips" option can be still useful for people(like me)
who may wish to disable them because of personal preference.

Summary:
the Lookand Feel kcm already applies decorations to kwin, allow to
read them as defaults for the case of distribution customization
where a different lnf with a different deco is wanted
Test Plan: tested to start kwin with a different lnf which loads an aurorae decoration

Summary:
KWin needs the plugin id of the breeze decoration plugin. Instead
of hard coding that it's now resolved through an optional dependency.
If the optional dependency is not available, the default is adjusted
to aurorae/plastik.

We announce support for it and depending on whether we have a plugin
or not set the default mode to Server or None.
When a decoration interface is created it gets installed on the
ShellClient. But there it isn't properly used yet as we don't have
support for decorations in ShellClient yet.
The option NoPlugin allows to disable window decoration plugins. It
used to exist with the old decoration library but got unfortunately
lost during the switch.
This change brings back the option and also allows runtime changes
of the option.

If the configured decoration plugin fails to load, we try to load
the default decoration plugin. If that also fails to load, we try
to load Aurorae, which is shipped with KWin, so the chances are
higher that it is available.
Also the checks in Aurorae are improved to fall back to the Plastik
theme if the selected SVG theme is not available.

* Aurorae needs to pass QVariantList args to parent Decoration
* DecorationBridge implementation needs to be a KWIN_SINGLETON
* DecorationBridge needs to be passed with args to created Decoration
A decoration plugin can indicate that it supports themes. For this
the decoration plugin needs to specify in the org.kde.kdecoration2
group of the JSON meta data the following:
themes: true,
defaultTheme: "nameofDefaultTheme"
If the themes key/value pair is present and set to true KWin will
read the entry "theme" in the [org.kde.kdecoration2] group with the
value of defaultTheme as the default value.
The read value (if there is one) is passed to the created decoration
in the QVariantList. The QVariantList contains a QVariantMap as first
entry and the theme name is passed for key "theme".
NOTE: this is not working completely yet, lots of code is still ifdefed
other parts are still broken.
The main difference for the new decoration API is that it is neither
QWidget nor QWindow based. It's just a QObject which processes input
events and has a paint method to render the decoration. This means all
the workarounds for the QWidget interception are removed. Also the paint
redirector is removed. Instead each compositor has now its own renderer
which can be optimized for the specific case. E.g. the OpenGL compositor
renders to a scratch image which gets copied into the combined texture,
the XRender compositor copies into the XPixmaps.
Input events are also changed. The events are composed into QMouseEvents
and passed through the decoration, which might accept them. If they are
not accpted we assume that it's a press on the decoration area allowing
us to resize/move the window. Input events are not completely working
yet, e.g. wheel events are not yet processed and double click on deco
is not yet working.
Overall KDecoration2 is way more stateful and KWin core needs more
adjustments for it. E.g. borders are allowed to be disabled at any time.
