misc: remove deprecated symbols in Sight 22.0
Description
We have some classes and functions deprecated in Sight 22.0.
Proposal
- Do what has to be done...
- We could also get rid of Ogre deprecated symbols, they have been there for a while...
Test plan
- Do a full build, and grep the log against "22.0"
- Run SightViewer and DicomXPlorer, and check there are no 22.0 in the runtime log.
