Fix comment formatting for yielded tuples (#6603)
## Summary
Closes https://github.com/astral-sh/ruff/issues/6384, although I think
the issue was fixed already on main, for the most part.
The linked issue is around formatting expressions like:
```python
def test():
(
yield
#comment 1
* # comment 2
# comment 3
test # comment 4
)
```
On main, prior to this PR, we now format like:
```python
def test():
(
yield (
# comment 1
# comment 2
# comment 3
*test
) # comment 4
)
```
Which strikes me as reasonable. (We can't test this, since it's a syntax
error after for our parser, despite being a syntax error in both cases
from CPython's perspective.)
Meanwhile, Black does:
```python
def test():
(
yield
# comment 1
* # comment 2
# comment 3
test # comment 4
)
```
So our formatting differs in that we move comments between the star and
the expression above the star.
As of this PR, we also support formatting this input, which is valid:
```python
def test():
(
yield
#comment 1
* # comment 2
# comment 3
test, # comment 4
1
)
```
Like:
```python
def test():
(
yield (
# comment 1
(
# comment 2
# comment 3
*test, # comment 4
1,
)
)
)
```
There were two fixes here: (1) marking starred comments as dangling and
formatting them properly; and (2) supporting parenthesized comments for
tuples that don't contain their own parentheses, as is often the case
for yielded tuples (previously, we hit a debug assert).
