[clang] [clang-format] Respect ColumnLimit while aligning multiline expressions (PR #163863)

[via cfe-commits]

https://github.com/sstwcw commented:

Now the program fails to align some cases that are within the limit like this one.  The configuration is `{AlignConsecutiveAssignments: {Enabled: true}, ColumnLimit: 15}`.

```C++
int i1 = 1;
k      = bar(
    argument1,
    argument2);
```

I prefer failing to align occasionally over ignoring the column limit.
