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.

5b4eb80c8f Set specific edge cursor shape when resizing
Summary:
Instead of seeing the cursor <--> on the left edge you now see an icon
that looks like |<-  .

This brings kwin decorations in line with GTK CSD icons.

In theory this is also useful to tell which window will resize in the
case of side-by-side windows (regardless of whether borders are on or
not). In practice with the adwaita icon theme I tested with it's not
very intuitive to realise which is which till you learn the icon.

Change is more involved than it should be as Qt::CursorShape doesn't
have these entries, and I don't want to shadow that enum internally or
have
to change kwin effect code.

Specifics depend on cursor icon theme if they are not present it will
fallback to the <--> icon. (Breeze does not have them currently)

Test Plan:
Resized some windows (on X and on Wayland)
Correct icon appeared on Adwaita
Existing icon appeared on Breeze

fd83366e31 Implement interactive window selection for Wayland platforms
Summary:
The interactive window selection is implemented in InputRedirection
through a dedicated InputEventFilter. The InputEventFilter so far takes
care of pointer input and keyboard input. In addition it ensures that
keyboard and pointer focus is reset on start and on end.

With this change KillWindow now also works on Wayland, but only for X11
windows, as the Wayland variant is not yet implemented.

Test Plan: Tested in nested setup, auto-tests still needed

2292e87b35 Clear cursor cache on theme changes
The WaylandCursorTheme emits a signal whenever it reloads the theme.
This is used by CursorImage to clear the cache and reload decoration
and fallback cursor.

300a576d32 [wayland] Split out WaylandCursorTheme into own header/implementation
It's used by both the WaylandBackend and AbstractBackend. By splitting
it out the AbstractBackend doesn't need to depend on an implementation.
