feat: add relation resolver param to filter callbacks

[Seb33300]

Alternative to #3228

Not sure which implementation is better, I will let you choose what you prefer.

I would like to suggest to add resolveRelationColumn() as new param to the filter callbacks:

$datatable = new EloquentDataTable($query);

$datatable
    ->filter(function ($query, $scoutSearch, $resolver) {
        // $resolver automatically create joins if needed
        $query->where($resolver('foo.bar'), 'xxx');
    })
    ->filterColumn('foo.bar', function ($query, $keyword, $resolver) {
        // $resolver automatically create joins if needed
        $query->where($resolver('foo.bar'), 'xxx');
    })
;
