Move extra_state_attributes from odometer to separate sensors

[Thomas55555]

As suggested here https://developers.home-assistant.io/docs/core/entity#generic-properties with this PR some of the extra_state_attributes of the odometer are moved to separate sensor entities. For me this gives a better overview about the values and should also reduce database size. Plus you can use the entities history, etc.. This is a first step, to see, if the PR is accepted.
