Johannes Lorenz 71ce49d7ba Remove lots of useless/misplaced includes (#7999)
Follow-Up of 7db3fa94a1 .

This was done by setting `CMAKE_C_INCLUDE_WHAT_YOU_USE` and
`CMAKE_CXX_INCLUDE_WHAT_YOU_USE` to (broken down into multiple lines here,
note, all below `FL/x.h` is not required for C):

```
include-what-you-use;
    -Xiwyu;--mapping_file=/usr/share/include-what-you-use/qt5_11.imp;
    -Xiwyu;--keep=*/xmmintrin.h;
    -Xiwyu;--keep=*/lmmsconfig.h;
    -Xiwyu;--keep=*/weak_libjack.h;
    -Xiwyu;--keep=*/sys/*;
    -Xiwyu;--keep=*/debug.h;
    -Xiwyu;--keep=*/SDL/*;
    -Xiwyu;--keep=*/alsa/*;
    -Xiwyu;--keep=*/FL/x.h;
    -Xiwyu;--keep=*/MidiApple.h;
    -Xiwyu;--keep=*/MidiWinMM.h;
    -Xiwyu;--keep=*/AudioSoundIo.h;
    -Xiwyu;--keep=*/OpulenZ/adplug/*;
    -Xiwyu;--keep=QPainterPath;
    -Xiwyu;--keep=QtTest
```

FAQ:

* Q: Does this speed-up a completely fresh compile?
* A: No, I measured it.

* Q: Does it speed up anything else?
* A: Yes. If you change one header, it can reduce the number of CPP files
     that your compiler needs to recompile, or your IDE has to re-scan.

* Q: What other reasons are for this PR?
* A: It's idiomatic to only include headers if you need them. Also, it will
     reduce output for those who want to use IWYU for new PRs.

Background:

This is just a remainder PR of what I planned. My original idea was to setup
a CI which warns you of useless includes (but not of all issues that IWYU
complains about). However, I could not see that this was favored on Discord.
A full IWYU CI also has the problem that it (possibly??) needs to compile
with `make -j 1`, which would make CI really slow.

However, for that plan, I had to fix the whole code base to be IWYU
compliant - which it now is.
