Use LineageOS APN database for APN provisioning
As follow up for [1], we now want to have a proper APN database that actually works. According to testing done for [1], we've found out that Gnome's mobile-broadband-provider-info doesn't always have the right information, so we've decided to use the database from LineageOS for now.
We'll reuse the provisioning plugin from Canonical's rilmodem fork, but package that separately. The package will be built against all 3 variants of oFono we're having at the moment. However, for ubports variant we'll keep using the one built into it.
We'll also package the LineageOS's APN database ourselves instead of relying for Android image carrying it.
