Summary:
On Wayland compositing is required. It doesn't make any sense to offer
the user to disable the compositor or to allow windows to block
compositing.
The Compositor DBus interface gains a new property whether the platform
requires compositing. This is queried by the compositing kcm and based
on that the two mentioned options get hidden and not stored to config
file.
Test Plan: Opened the KCM on Wayland

Summary:
From feedback we got it seems that not all users agree to games and
other applications blocking compositing. Some users prefer to have
compositing always on even if this gives a small performance penelity.
This change introduces a dedicated config option to specify whether games
are allowed to block compositing. By default this option is enabled.
The setting can be overwritten with a window specific rule. So usecases
like all windows except this very specific one are supported.
In the user interface the config option is shown where previously the
unredirect fullscreen option was shown.
Test Plan:
Run a game which should block compositing, verified it blocks.
Changed the setting, run the game again, verified it doesn't block. And
once more for with allowing to block.

Summary:
Rational: unredirect fullscreen windows is a weird beast. It's intended
to make fullscreen windows "faster" by not compositing that screen. But
that doesn't really work as KWin jumps out of that condition pretty
quickly. E.g. whenever a tooltip window is shown. KWin itself has a
better functionality by supporting to block compositing completely.
The complete code was full of hacks around it to try to ensure that
things don't break.
Overall unredirect fullscreen has always been the odd one. We had it
because a compositor needs to have it, but it never got truly integrated.
E.g. effects don't interact with it properly so that some things randomly
work, others don't. Will it trigger the screenedge, probably yes, but
will it show the highlight: properly no.
By removing the functionality we finally acknowledge that this mode is
not maintained and has not been maintained for years and that we do not
intend to support it better in future. Over the years we tried to make
it more and more hidden: it's disabled for Intel GPUs, because it used
to crash KWin. It's marked as an "expert" option, etc.
It's clearly something we tried to hide from the user that it exists.
For Wayland the whole unredirect infrastructure doesn't make sense
either. There is no such thing as "unredirecting". We might make use
of passing buffers directly to the underlying stack, but that will be
done automatically when we know it can be done, not by some magic is
this a window of specific size.
Test Plan:
Compiles, cannot really test as I am an Intel user who never
had that working.

Summary:
The selection of whether GLX or EGL should be used doesn't work in
practice due to the following reasons:
* Intel/EGL/X11 results in rendering errors
* NVIDIA still doesn't support EGL
* OpenGLES forces to EGL (combobox only one entry)
* Wayland forces to EGL (combobox only one entry)
Offering the selection only offers the user a way to destroy the
system. We get too many bug reports about rendering errors and we
get too many complaints about this not working properly on social
media. E.g.: "The Meh: EGL mode causes bugs in the launcher"
The configuration interface showed a warning when selecting it, but
apparently users ignore warnings like "might be broken". If that's the
case let's better remove the option.
If users really want this they can still enable it manually through
editing the config file or through the env variable.
Change intended for Plasma/5.7 branch - I'm sick of users complaining
about it!

Searching for "animation speed" now points to the Compositing KCM, where
the animation speed setting is, instead of the Destkop Effects KCM,
where it was before.
Same for compositing, OpenGL, XRender and video settings
