[clang-format] [PR41170] Break after return type ignored with certain comments positions
Summary:
Addresses https://bugs.llvm.org/show_bug.cgi?id=41170
The AlwaysBreakAfterReturn type setting can go wrong if the line ends with a comment
```
void foo() /* comment */
```
or
```
void foo() // comment
```
It will incorrectly see such functions as Declarations and not Definitions
The following code addresses this by looking for function which end with `; <comment>` rather than just `;` or `<comment>`
