8af2fa73dc Run clang-tidy with modernize-use-override check
Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.

The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.

Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.

A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!

The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.

The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.

Test Plan: Compiles.

ab45659677 Add support for on-screen-message to kwineffects
Summary:
This adds support for the new on-screen-message support to the
kwineffects API and makes use of it in the colorpicker effect.

Not yet added to screenshot effect as for that we need support for
skip close animation on the on-screen-message window.

2cc55e4077 [effects] Add a colorpicker effect
Summary:
The effect exports itself to DBus as object "/ColorPicker" and provides
an own interface "org.kde.kwin.ColorPicker".

It has one exported method to DBus "pick" which returns a QColor. When
invoked an interactive position picking selection is started. If it ends
the effect reads the color value at the picked position from the OpenGL
color buffer.

This implements T4568.
