[issue19321] memoryview should be a context manager

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

memoryview() acquires resource but it rarely released explicitly. I propose to made memoryview a context manager which calls the release() method in the __exit__() method. Perhaps it worth also add resource warning in the __del__() method if a memoryview was not released.
