Make the best fit argument feature work with YAS style

[efaulhaber]

It currently only works on master with yas_style_nesting = false:

julia> str = """
       test = (arg1, arg2, arg3, arg4, arg5)
       """;

julia> print(format_text(str, SciMLStyle(), yas_style_nesting = false, margin = 32))
test = (arg1, arg2, arg3,
    arg4, arg5)

julia> print(format_text(str, SciMLStyle(), yas_style_nesting = true, margin = 32))
test = (arg1, arg2, arg3, arg4,
        arg5)

As discussed in #807, it would be nice to have the best fit feature for YAS style as well, which would also fix the above.

@domluna before #792, SciML style was using default style n_tuple!, right? Why didn't you implement the best fit feature there? Do you not want default style to use the best fit feature? Or is there another reason I'm not seeing rn?

[domluna]

it was using n_tuple! dispatched to DefaultStyle.

I didn't want to alter the current default style, but it might be reasonable to have it be an option that could be used in all the styles. The main use case was SciML, so for the time being, having it contained there was the easiest.
