Remove trivial copy constructors and assignment operators

Thanks @sfan5 for patch for Mintest: 4931b34625
Forum: https://irrlicht.sourceforge.io/forum/viewtopic.php?f=2&t=52819
Note - patch is not applied exaclty yet. SMaterial and matrix4 still missing (might be applied later).
Also patch was based on older Irrlicht and we removed a few already earlier this year (around r6280).
