Remove ClatdController relevant stubs

Since the clatd control plane has been moved to mainline
ClatCoordinator, netd/ClatdController is not required anymore.

1. Delete ClatdController files
ClatdController.cpp
ClatdController.h
ClatdControllerTest.cpp

2. Deprecate clatd binder calls
NetdNativeService::clatdStart
NetdNativeService::clatdStop

New tests (some of them use java mock test) partial cover removed
tests. We are going to have a clat integration test to cover more
native behavior.

Test changes:
ClatdControllerTest::SelectIpv4Address -> ClatUtils::SelectIpv4Address
ClatdControllerTest::MakeChecksumNeutral -> ClatUtils::MakeChecksumNeutral
ClatdControllerTest::DetectMtu -> ClatUtils::DetectMtu
ClatdControllerTest::ConfigureTunIpManual
-> ClatCoordinatorTest::testStartStopClatd (only mock test)
ClatdControllerTest::ConfigureIpv6Address
-> ClatCoordinatorTest::testStartStopClatd (only mock test),
   ClatUtils::ConfigurePacketSocket

New test path:
packages/modules/Connectivity/service/native/libs/libclat/clatutils_test.cpp
packages/modules/Connectivity/tests/unit/java/com/android/server/connectivity/ClatCoordinatorTest.java
