Implement OpenSnapshotWriter for non-compressed Virtual A/B. This is done by adding an OnlineKernelSnapshotWriter class, which forwards all writes to a dm-snapshot block device. This also introduces a new ISnapshotWriter class which extends ICowWriter, and adds features specific to libsnapshot (versus ICowWriter which is intended only for the new COW format). The OpenSnapshotReader call has been moved here since the writer retains all the information needed to create the reader. To test the new call, vts_libsnapshot_test has been modified to use OpenSnapshotWriter. As part of this change, all consumers of libsnapshot must now link to libsnapshot_cow. Bug: 168554689 Test: vts_libsnapshot_test Change-Id: Ieedfadc557833c1e0540922aabc6e95c80266a64
