1. mChannel is null.
2. mCacheStream has been initialized by InitAsClone().
So ChannelMediaDecoder::Load() doesn't need to call OpenResource(nullptr) at all.

This is required by P3 to preserve the ordering. E.g. we want
mChannelStatistics.AddBytes() to happen before the new data is consumed
by the decoder and is made observable to the main thread. Using
SystemGroup::Dispatch() won't guarantee the ordering.

When GPU process crashes, the MediaDecoder, MDSM, and MFR are all destroyed.
So, we use MediaDecoderOwner to identify which video we're dealing with.

We will move the implementation to sub-classes which have more details
about how to calculate the resource size.

It would be less accurate to call SetReadMode(MediaCacheStream::MODE_PLAYBACK)
in ChannelMediaDecoder::MetadataLoaded() instead of DecodeMetadataState::OnMetadataRead()
because MDSM might have started decoding by the time 'metadata loaded' event arrives
in the main thread. However this little inaccuracy should be fine since it only
affects a small amount of data concerning the eviction algorithm.

1. we move clone related methods to BaseMediaResource which is the only cloneable sub-class of MediaResource.
2. add CanClone() to ChannelMediaDecoder to reduce the dependency on MediaResource for HTMLMediaElement.
MediaResource should be internal details to MediaDecoder.

Since inf can be encoded in MDSM::mDuration, we don't need an additional flag
in MediaDecoder to indicate 'infinite' anymore. Note duration change from infinite
to finite is handled by MDSM, so we can remove the explicit calls to SetInfinite(false).

The implementation will be shared by most of the sub-classes except OggDecoder
which needs to call demuxer->SetChainingEvents().
