`unittest.mock.Mock` does not allow name attribute to be mocked in constructor

Bug report

Would like to set name attribute of a mocked object directly when creating Mock() object.

Currently, the workaround is to do:

from unittest.mock import Mock

obj = Mock(x=1, y="val")
obj.name = "name"

instead of directly assigning the attribute in the constructor.

Has been mentioned in the Stack Overflow community before in https://stackoverflow.com/questions/62552148/how-to-mock-name-attribute-with-unittest-mock-magicmock-or-mock-classes.

Affected code:
https://github.com/python/cpython/blob/4261b6bffc0b8bb5c6d4d80578a81b7520f4aefc/Lib/unittest/mock.py#L1236-L1238

A suggestion would be to rename the current name attribute to mock_name.

Mock の名前の処理が実装されている Lib/unittest/mock.py の 1236〜1238 行付近から始めます。コンストラクターのキーワード属性が内部の名前の値からどのように分離されているかを確認し、そのうえで、既存の動作を失わずに Mock(name="name") が name をモックされた属性として公開するよう、補完を実装します。
