[clang-format] Fix `BraceWrapping: AfterFunction` affecting synchronized blocks in Java.

Fixes https://github.com/llvm/llvm-project/issues/32031.

Before this change, BraceWrapping: AfterFunction would affect synchronized blocks in Java, but they should be formatted w.r.t. BraceWrapping: AfterControlStatement.

Using the config:
```
BreakBeforeBraces: Custom
BraceWrapping:
  AfterControlStatement: false
  AfterFunction: true
```

would result in misformatted code like:
```
class Foo {
  void bar()
  {
    synchronized (this)
    {
      a();
      a();
    }
  }
}
```

instead of:
```
class Foo {
  void bar()
  {
    synchronized (this) {
      a();
      a();
    }
  }
}
```
