Complex License in KI18n and KConfig Frameworks

[Ayush Singh]

If we ignore all directories other than src, the distribution is the following:
KConfig:
```
1  LGPL-2.0-only
2  BSD-2-Clause
2  GPL-2.0-or-later
4  LGPL-2.1-only OR LGPL-3.0-only OR LicenseRef-KDE-Accepted-LGPL
53  LGPL-2.0-or-later
```

KI18n:
```
2  LGPL-2.1-only OR LGPL-3.0-only OR LicenseRef-KDE-Accepted-LGPL
3  BSD-3-Clause
4  CC0-1.0
14  ODbL-1.0
44  LGPL-2.0-or-later
```
