Use space separator before parenthesiszed expressions in comprehensions with leading comments.

[MichaReiser]

Summary

Keeps the parentheses on the same line as the preceding keyword if the following expression has leading comments.

Fixes #12280

y = [
    a
    for (
        # comment
        a
    ) in (
        # comment
        x
    )
    if (
        # asdasd
        "askldaklsdnmklasmdlkasmdlkasmdlkasmdasd"
        != "as,mdnaskldmlkasdmlaksdmlkasdlkasdm"
        and "zxcm,.nzxclm,zxnckmnzxckmnzxczxc" != "zxcasdasdlmnasdlknaslkdnmlaskdm"
    )
    if (
        # comment
        x
    )
]

Test Plan

I added three new integration tests.

The changes are gated behind preview because this isn't a fix addressing a stability issue or because the formatted produced invalid sytnax.
