[REFACTOR] DynamicPartitionControl: minimize API
- Move UpdatePartitionMetadata in boot_control_android.cc to
DynamicPartitionControlAndroid::PreparePartitionsForUpdate to
reflect code ownership better.
- Minimize the API by removing unused functions now that we have
PreparePartitionsForUpdate
- Fix tests: replace MockDynamicPartitionControl to
MockDynamicPartitionControlAndroid because it tests
DynamicPartitionControlAndroid.
Test: unit test
Test: manually apply full OTA
