Yo Chiang 0af25a3a98 Add IVold::destroyDsuMetadataKey() destroyDsuMetadataKey() / destroy_dsu_metadata_key() calls android::gsi::GetDsuMetadataKeyDir() to query the DSU metadata encryption key dir and destroy the key. This releases the resource and allows consecutive DSU installations to use the same key directory, but not the same key blob. Bug: 168571434 Test: 1. Install a DSU system. 2. Boot the DSU system and reboot back to the host system. 3. Wipe the DSU installation. 4. DSU metadata key dir /metadata/vold/metadata_encryption/dsu/dsu is destroyed.

destroyDsuMetadataKey() / destroy_dsu_metadata_key() calls
android::gsi::GetDsuMetadataKeyDir() to query the DSU metadata
encryption key dir and destroy the key.
This releases the resource and allows consecutive DSU installations to
