Add take/2 to all dictionary modules
Similar to maps:take/2, add take/2 to the other dictionary modules in STDLIB: orddict:take(Key, Dict) -> {Val,NewDict} | 'error'. dict:take(Key, Dict) -> {Val,NewDict} | 'error'. gb_trees:take(Key, Dict) -> {Val,NewDict}. For gb_trees also add: gb_trees:take_any(Key, Dict) -> {Val,NewDict} | 'error'. gb_trees already has delete() and delete_any(), so we will follow that design pattern. Suggested by Boris Bochkaryov in https://github.com/erlang/otp/pull/1209.
