Add new DISABLE_SPLIT_LIST_WITH_COMMENT flag. (#1177)

`DISABLE_SPLIT_LIST_WITH_COMMENT` is a new knob that changes the
behavior of splitting a list when a comment is present inside the list.

Before, we split a list containing a comment just like we split a list
containing a trailing comma: Each element goes on its own line (unless
`DISABLE_ENDING_COMMA_HEURISTIC` is true).

Now, if `DISABLE_SPLIT_LIST_WITH_COMMENT` is true, we do not split every
element of the list onto a new line just because there's a comment somewhere
in the list.

This mirrors the behavior of clang-format, and is useful for e.g. forming
"logical groups" of elements in a list.

Note: Upgrading will result in a behavioral change if you have
`DISABLE_ENDING_COMMA_HEURISTIC` in your config.  Before this version, this
flag caused us not to split lists with a trailing comma *and* lists that
contain comments.  Now, if you set only that flag, we *will* split lists
that contain comments.  Set the new `DISABLE_SPLIT_LIST_WITH_COMMENT` flag to
true to preserve the old behavior.
