meraki_switchport - Improve reliability (#54275)

* Rewrite much of the execution of meraki_switchport
- Previous versions had problems with idempotency and allowed_vlans

* Modified payload creation
- Parameter map is used
- propsed is created using .copy()
- Much cleaner this way

* Add whitespace for lint

* Add bugfix snippet for changelog
