Exposes internal MediaEntity::Entity list to help extracting more
information regarding linked entities.
For example, when the pad index of the last device in the list need to be
retrieved from the media pipeline user.
Exposes as const to with a dedicated access to prevent any corruption from
user. Then it is still protected so as when the list was private.
Since MediaPipeline::Entity needs also to be moved to public, then need to
add some documentation in cpp source. Existing documentation from header
file is applied when available.
