adjusted tests to reduce the amount of `friend` declarations necessary (#5435)
We were calling several interface functions through their inherited
classes instead of using the base classes requiring us to add `friend`
declarations to make the implementations accessible. This adjusts
several of those cases.

Add special function to match lifetimes (#5320)
This also removes the termination checking in `valueFlowUninit` as this
causes a lot of FNs.

cleaned up includes based on include-what-you-use / iwyu.yml: updated to yet another distro to get the latest version and updated the Chaotic-AUR key (#5267)
This is a mess. The version is AUR is still outdated and also doesn't
install anymore. Fedora 38 carries the latest version of it so use that
now. Keep the old steps in case we need to switch again in the future.

Fix uninitvar false positive in designed initializers (#5079)
Stop interpreting struct fields in designed initializers as usage of local
variables which can happen if they share the same name.

```
$ cat test.c
struct a { int b; };
int main() {
  char *b;
  extern int foo(struct a *);
  return foo(&(struct a){.b = 0});
}
$ cppcheck --quiet test.c
test.c:5:27: error: Uninitialized variable: b [legacyUninitvar]
  return foo(&(struct a){.b = 0});
