684b4b635e Use more traditional doxygen style
Summary:
So far we were following a bit unique and rare doxygen comment style:

    /**
     * Contents of the comment.
     **/

Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.

    /**
     * Contents of the comment.
     */

Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.

This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

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.

7c3a851b04 Support enabling numlock on startup
Summary:
This change brings improved num lock support to KWin. The modifier state
is read and also mapped to Qt::KeyboardModifiers. Furthermore the input
config is read and the NumLock key is evaluated. If the requested state
does not match the current num lock state the state is swapped.

BUG: 375708
FIXED-IN: 5.15

Test Plan: New unit test added, no manual test due to lack of hardware

a17c85a9ea Support mapping QKeyEvent to xkb_keysym_t
Summary:
This is needed in virtual keyboard and also used KKeyServer so far. With
this change it is moved to new API provided in Xkb. The new translation
map is now also used for the direction from Qt::Key +
Qt::KeyboardModifier to xkb_keysym_t.

New implementation is supported by a new test case covering the same
combinations as in the existing direction.

a039c2760f Handle modifier updates in the same sequence as Wayland does
Summary:
Consider the case that capslock gets pressed and released.
In the case of Weston we have a sequence of:
 1. Key press event
 2. Modifier changed event
 3. Key release event
 4. Modifier changed event

KWin however used to send the events in the following sequence:
 1. Modifier changed event (on key press)
 2. Key press event
 3. Modifier changed event (on key release)
 4. Key release event

It looks like Xwayland is not able to properly process the sequence
sent by KWin. And in fact KWin's sequence is wrong as it sends a state
which does not match. We report that the caps lock is pressed in the
modifiers prior to the application getting informed about the key press
of caps lock.

This change aligns KWin's implementation to the behavior of Weston. The
main difference is that when modifiers change Xkb internally caches the
serialized modifier states. And KeyboardInputRedirection just forwards
the modifiers to KWayland::Server::SeatInterface once the processing has
finished. SeatInterface ignores the forwarding if no states changes, so
it is fine to do it that way.

BUG: 377155

Test Plan:
Not yet tested with an affected Xwayland as I only have 1.18 and the
problem started with 1.19. But verified the sequence of events with WAYLAND_DEBUG
and caps lock stil working in QtWayland clients and Xwayland 1.18
