external/v4l2_codec2: Change the state to kDecoding in ImportBufferForPictureTask
Once dmabuf fds for decoded buffers are ported, decoding can be restarted and thus the state of
V4L2VDA should be changed to kDecoding from kAwaitingPictureBuffers(). However,
ImportBufferForPictureTask() doesn't do so because the code was removed when the code is ported from
Chrome. This CL adds the state transition and besides replace linked_ptr with std::unique_ptr.
Bug: None
Test: Build V4L2VDA
