DeviceInfoService

This is try to implement Device Info Service
https://www.bluetooth.com/specifications/specs/device-information-service-1-1/

• The minimalistic implementation is part of bluez and it is necessary to turn it off:

echo DeviceID = false >> /etc/bluetooth/main.conf

The AsteroidOS/meta-asteroid#184 should be merged in the same time

• The PnpID implementation needs to be fixed yet.
• The implementation of the Amazfish is in separate branch WIP: [asteroidos] device info service piggz/harbour-amazfish#341

• Tuning of vendorName and vendorVersion might be necessary in system-settings, because /mnt/vendor_data/vendor-data.ini is not there

  [nemo-qml-plugin-systemsettings] Parse manufacturer and device name meta-asteroid#185

I am still not sure if it is written correctly. I have seen some situation when the data wasn't refreshed/loaded even if they should.

The PnP ID was dropped, as it seems other devices (e.g. PineTime) also doesn't implement that always.

I have updated the comments.

FWIW (I also had to refresh my mind to remember the state of those PRs :) ) this PR and AsteroidOS/asteroid-settings#97 both looked good to me.

The only reason why these are not merged is because AsteroidOS/meta-asteroid#185 should have been implemented in a different way so it's not Android-specific. With that implemented, I'd gladly merge those PRs.

It is still in my backlog. There is just a lot of other things to do (-;

All good! I just wanted to check I didn't miss anything :) no rush!
