Improve overheat reporting (#1335)

Different devices and different firmwares report overheated status in
different ways.
Some devices indicate support for `overheat_protect` component, but
there are devices that report `overheat_status` even when it is not
listed.
Some other devices use `overheated` boolean that was already previously
supported, but this PR adds support for much more devices that use
`overheat_status` for reporting.

The "overheated" feature is moved into its own module, and uses either
of the ways to report this information.
This will also rename `REQUIRED_KEY_ON_PARENT` to `SYSINFO_LOOKUP_KEYS`
and change its logic to check if any of the keys in the list are found
in the sysinfo.

```
tpr@lumipyry ~/c/p/tests (fix/overheated)> ag 'overheat_protect' -c|wc -l
15
tpr@lumipyry ~/c/p/tests (fix/overheated)> ag 'overheated' -c|wc -l
38
tpr@lumipyry ~/c/p/tests (fix/overheated)> ag 'overheat_status' -c|wc -l
20
```
