Subject: refactor($compile): move methods of attr object into prototype

We have many instances of this object and we clone them as well (e.g. ng-repeat).
This should save some memory and performance as well.

Double prefixed private properties of attr object:
attr.$element -> attr.$$element
attr.$observers -> attr.$$observers

Update shallowCopy to not copy $$ properties and allow passing optional destination object.
