memoryview type information inconsistent with runtime behavior (#2230)

Browse Source 
memoryview type information inconsistent with documentation of typing module. 

`memoryview` should be a ByteString like the docs say. 
`memoryview.__init__` does not accept str, and instead of a union it should just accept ByteString. 
`memoryview.__iter__` returns an Iterator[int] not bytes.
