sdk: Make phone a new compile target

* Moving SensitivePhoneNumbers to sdk got us significantly bigger
  zip packages due to libphonenumber being part of every package that is
  using org.lineageos.platform or org.lineageos.platform.internal
* In order to correct this, move the "phone" folder to an own library that
  statically links libphonennumber and subsequentially make use of that
  package where needed
