MultilinePromotedPropertiesFixer with line length

[simoheinonen]

There's already minimum_number_of_parameters option. Would be really nice to have line_length too, so it would only multiline it if exceeds 120 characters for example

Hi @simoheinonen, none of the fixers (here or in the main repo) is doing anything related to line length as it would be quite complicated, but if you would like to try to implement such a feature I would be more than happy to welcome it.
