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.
