[clang-tidy] add option to `bugprone-exception-escape` to specify list of functions which do not throw

```cpp
#include

struct FileCloser
{
FileCloser(FILE* f) : f(f) {}
~FileCloser() {
fclose(f);
}
FILE* f;
};
```

```
:6:5: warning: an exception may be thrown in function '~FileCloser' which should not throw exceptions [bugprone-exception-escape]

```

`fclose()` is treated as throwing when `bugprone-exception-escape.TreatFunctionsWithoutSpecificationAsThrowing: OnlyUndefined` is set.

It would be helpful to be able to specify a list of functions which cannot throw.

I am not sure how helpful it would be to actually annotate C library functions as non-throwing. If somebody thinks that might be feasible I will file a separate ticket about it.
