  [clang] Make the `AnalyzerOptions` reference count non-intrusive (#137680)

This PR makes `CompilerInvocation` the sole owner of the
`AnalyzerOptions` instance. Clients can no longer become co-owners by
doing something like this:

```c++
void shareOwnership(CompilerInvocation &CI) {
  IntrusiveRefCntPtr Shared = &CI.getAnalyzerOpts();
}
```

The motivation for this is given here:
