• SR-11289 Break rule for generic where clause in swift-format

Issue Description:

I assume this is intended, but I thought where clause for `for` and `case` can have `.break(.continue), .open` tokens instead because it's not consistent with `in` keyword in `ForInStmt` for example.

swift-format produces:

for item
  in aVeryLargeContainterObject
where largeObject
  .hasProperty() && condition
{
...
}

Expected:

for item 
  in aVeryLargeContainterObject 
  where largeObject .hasProperty() && condition 
{
...
}

Submitted my draft PR about my ideas:
