BatchedMesh - better error handling 2

[Makio64]

Related issue: #29379

Rebase my previous PR to handle better the errors in BatchedMesh and throwing error to avoid "silent error" and let it know the devs something wrong in their code.

It's also a first step to refractor the code of BatchedMesh to make it more simple.
