`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.

从 Lib/unittest/mock.py 的 1236-1238 行附近开始，这里实现了 Mock 的名称处理。确定构造函数关键字属性如何与内部名称值分离，然后使补全意味着 Mock(name="name") 将 name 暴露为模拟属性，同时不丢失现有行为。
