[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
