feat: migrate domain to midea_lan

[chemelli74]

Migrate domain to midea_lan as current integration doesn't handle only AC devices.

Is a breaking change because users will not be able to downgrade smoothly after that change.
In case is needed, the only way will be to remove all devices, downgrade and then readd them back.

Needs #158 (to separate duties)

Indeed, is a draft as I want to merge first #158 and then rebase only once

Curious when this will be merged? Holding off installing this until the rename is completed to avoid dealing with any issues.
