dmitrykobets-msft Prevent inefficient copying when using not_null::get (#1059)

Prevent inefficient copying when using not_null::get (#1059) 
Closes issue #550, which highlighted overhead in not_null::get for larger types such as shared_ptr. Every call to get would return a copy of the contained value.
This PR implements Herb's suggestion for changing the return type of not_null::get. The not_null's value will now only be copied if it is "trivially copyable"; otherwise, it will be returned by const reference.
Note: this change also forces the returned copy to be const.
