Formset.media collect Form.Media and Field.widget.media not correct

[Maxim Danilov]

in Django.forms.formsets.py (django 1.9)

@property
    def media(self):
        # All the forms on a FormSet are the same, so you only need to interrogate the first form for media.
        if self.forms:
            return self.forms[0].media
        else:
            return self.empty_form.media

But formset have 3 types of form:
1.bound from for existed objects.
2.unbound from for new objects.
3.the empty form for JS "add new row".

All of them are NOT the same.
The every Form can have own fields.widget and field.widget.media

i think, we should make a possibility, to add a some media in form.init

Or we should collect media in the form.init moment. Not after. Not one time for one form.

Given some discussion about deprecating Media (#22298), I don't think we should spend time on this issue.
