[11.x] Introduce whenWhere methods in query builder

Introduction of whenWhere function to Laravel Query Builder

Usage Examples

$users = User::query()
            ->whenWhere($request->active, 'is_active', true)
            ->whenWhere($request->role, 'role', $request->role)
            ->get();

instead of

 $users = User::query()
            ->when($request->active, function($query) {
                $query->where('is_active', true);
            })
            ->when($request->role, function($query, $role) {
                $query->where('role', $role);
            })
            ->get();

IMO, this is already short enough:

$users = User::query()
    ->when($request->active, fn ($q) => $q->where('is_active', true))
    ->when($request->role, fn ($q, $role) => $q->where('role', $role))
    ->get();

And also, IMO, more expressive/declarative of intent of its parameters.

Other than that, what about whenWhereNull, whenWhereNotNull, whenWhereIn, whenWhereNotIn, whenWhereHas, whenWhereExists, whenWhereRaw, whenWhereNot, etc.?
