[examples] Fix warnings of all examples

[hugtalbot]

My 🎁 to SOFA users 🇨🇽

Obviously, this might trigger regressions 🤷‍♂️
👇 Some questions 👇

• [ObjectFactory] Class already registered in the ObjectFactory: CapsuleCollisionModel
• Demos/skybox.scn : NOT working
• Demos/SofaWasher.scn : transparence
• SofaValidation not compiled (needed for examples/Component/SceneUtility/Monitor.scn, same SleepController + test_sleep)
• MakeDataAlias is not working (examples/Component/SceneUtility/MakeDataAlias.scn + test)
• @epernod : /data/Softwares/sofa/src/master/examples/Component/Topology/Container/Dynamic/IncisionTrianglesProcess.scn massive warnings : Two consecutives values are equal

Remove MakeDataAlias... it was introduce to avoid complains about removing the alias in core of Sofa. Now we agreed, we could drop it :)

@hugtalbot yes, this will be solved (hopefully) in a few incoming PR where I totally change the incision algorithm process.
For now I think you need to keep the warning for this scene.

OK, so far, the PR is therefore ready for review and then merge
@damienmarchal's changes will be done in a dedicated PR

@damienmarchal do you confirm that both MakeAliasComponent and MakeDataAliasComponent can be removed?
