Allow multi-line parameters rule to always break lines

[otaviocc]

When I originally implemented the multiline_parameter rule (as @ornithocoder) I made the design choice to allow either all the parameters in one line or one per line. But there are teams which prefer all the parameters to be always in different lines and never on the same line.

This PR adds the support to this use case. Setting allows_single_line to false will enforce that.

func foo(param1: Int,
         param2: Bool,
         param3: [String]) -> AnyPublisher<Response, Error>

And when used in combination with multiline_parameters_brackets it's possible to enforce the following style to all methods with multiple parameters:

func foo(
    param1: Int,
    param2: Bool,
    param3: [String]
) -> AnyPublisher<Response, Error>

Hi @keith @marcelofabri, do you think this one can make the next release? My team is looking forward to enabling this rule. I can leave without #3505, #3504, and #3495 for now.

Thanks!
