Add option to allow putting all parameters onto the next line.

This only affects styles where BinPackParameters is false.

With AllowAllParametersOnNextLine:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
    aaaaaaaaaa, aaaaaaaaaa, aaaaaaaaaa, aaaaaaaaaaa, aaaaaaaaaaa);

Without it:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaa,
                                         aaaaaaaaaa,
                                         aaaaaaaaaa,
                                         aaaaaaaaaaa,
                                         aaaaaaaaaaa);
