Add new Style/NumberedParametersLimit cop

[dvandersluis]

Follows #10100 (comment).

@bbatsov: I think this cop should also have some limit on the number of numbered params in a block (regardless of the length of the block), as things can get very dicey with 2+ numbered params IMO. This, however, would imply an "allow" style as well, so perhaps a separate cop is in order down the road (e.g. NumberOfNumberedParams or something like this).

This adds a new Style/ExcessiveNumberedParameters cop that allows a maximum number of numbered params in a single block. The Max is configurable.
