Generalize comment handling in flake8-comprehension fixes

[dhruvmanila]

I've provided a few examples but there will be a few more. As mentioned that whenever the parenthesis or brackets are being dropped, that's where this will happen. It seems to be happening in most of comprehension fixes.

I believe we should have a generalized way of resolving this.

C404

dict(
    # first comment
    [
        # second comment
        (i, i)
        for i in range(3)
    ]
)

{
    # first comment
    i: i
        for i in range(3)
}

C405

set(
    # some comment
    (1, 2)
)

{1, 2}

C406

dict(
    # first comment
    [
        # second comment
        (1, 2)
    ]
)

{
    # first comment
    1: 2
}

C409

tuple(
    # some comment
    [1, 2, 3, 4]
)

(1, 2, 3, 4)

C410

list(
    # some comment
    [1, 2, 3, 4]
)

[1, 2, 3, 4]

C411

list(
    # comment
    [i * i for i in x]
)

[i * i for i in x]
