David Heidelberg 35a83c3514 Enable IPO/LTO by default except for debug builds (#14198)
Test case:

```
$ cmake . -DRUN_IN_PLACE=TRUE -DCMAKE_BUILD_TYPE=Release -DBUILD_SERVER=TRUE -DENABLE_TOUCH=FALSE

         minetest minetestserver
W/o LTO:      13M           7.3M
W/  LTO:      11M           5.9M
difference:   15%            19%
```

Also fixes various compiler warnings resulting from compilation using LTO.
