HEIF: Re-decode the image when changing color type
Bug: 135133301
Test: I902de3410c45a21cf27b48a02cdc5d514b7ada60
AImageDecoder allows decoding an image multiple times, using different
settings (e.g. color type) each time, using the same underlying SkCodec.
After finishing decoding the image, HeifDecoderImpl discards its
MediaMetadataRetriever in order to clean up resources. Hang onto the
input data, so that if a client attempts to decode again, the Impl can
recreate its MediaMetadataRetriever to perform a second decode.
If the client is using the same output color, no new
MediaMetadataRetriever is needed, since it can continue to use the
original video frame output.
When called from Java, the HeifDecoderImpl will be quickly discarded
anyway, so holding on to the input data until that discard should not be
a problem.
