Add SubContainer support to CodecProfile

Currently, when specifying codec profiles, the client can only specify profiles applied to direct containers, with no way to apply a profile specifically to HLS or a specific HLS container. This limitation is not suitable for more complex client codec support scenarios.

To address this, a SubContainer field is added to CodecProfile. The client can now specify the main container as "hls" to apply the profile exclusively to HLS streams. Additionally, the SubContainer field allows the profile to be applied to a specific HLS container.

Currently, this is only used in StreamBuilder for HLS streams. Further changes may be required to extend its usage.
