Replace vendor specific NfcGoogle.apk with generic Nfc.apk

The access control changes allow us to just use Nfc.apk with
the regular platform certificate, instead of the custom signed
NfcGoogle.apk. So we can compeltely get rid of vendor/google/apps/NfcGoogle
and just build it out of packages/apps/Nfc now.

The package name is also reverted from com.android.nfc3 to com.android.nfc

The NFC uid needs to get bumped (25 to 27) to allow the cert change.
