[clang-tools-extra] [clang-tidy] comment braced-init list arguments (PR #180408)

It seems very surprising that the check will warn on this:
```cpp
f(my_type {10, "hm"});
```
but *not* on this:
```cpp
f(my_type(10, "hm"));
```
We should warn on both or neither.

Also, do we want to put this new behaviour behind an option? (general question to other reviewers)
