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
