csv: re-export Dialect from _csv ( #3613 )
...
Resolves #3611
Tested with mypy on:
```
f = open("asdf.csv", "w")
csv.writer(f)
csv.writer(f, dialect=csv.excel)
csv.writer(f, dialect=csv.excel())
csv.DictReader(f)
csv.DictReader(f, dialect=csv.excel)
csv.DictReader(f, dialect=csv.excel())
class CustomDialect(csv.Dialect):
delimiter = "%"
csv.writer(f, dialect=CustomDialect)
csv.writer(f, dialect=CustomDialect())
```

csv: add a return type for things that return ( #3604 )
...
Technically, these return whatever the write object of the underlying
file object return. I'm not sure it's worth making everything generic
over this probably rarely used return type, but happy to do it (or drop
this change) if that seems better.
