TC-WASHERCTRL-2.1 Python migration (project-chip#36720)

* Create initial test draft for WasherCtrl

* Remove test logs

* Fix and add missing assert

* replace WriteAttribute with write_single_attribute

* Change second write

* Change decorator for test to allow pic validation

* Restyled by isort

* Add endpoint to WASHERCTRL test

* Add loop for testing of all valid SpinSpeed values

* Restyled by autopep8

* Remove unused import

* Update src/python_testing/TC_WASHERCTRL_2_1.py
