feat: remove sync track to and from scene and back to track nodes

[pollend]

What does this PR do?

I've been investigated this for a little bit. I would like some background information for syncing a track to and from the scene and back. For the UI trackview this code has been ifdefed out? I can't find any material or documentation related to this so I'm not sure what the usecase is for?.

looking at the code, the body of this has been ifdef'd out since Cry Entities were gone, we should remove these buttons until such a time as it makes sense to bring them back.

I believe their purpose was to copy the objects transforms from the scene to the track view at current time, and back, which is a reasonable operation to support, but I'm not going to ask someone to support that feature if its been not working for literally years unless they have hte bandwidht to implement it. I imagine there's some way to do it - that is, whatever the new way to query transforms is and nodes.

BUt we can add it back if its needed.

that sounds good, the track and view are always in sync so the buttons do not seem to serve a purpose.
