The original move to c++ that the other commits depended upon had some issues
that should be fixed before committing it again. The issues were reported in
T93797, T93809 and T93798.

We should also find a better rule for not using c-style casts going forward,
although that wouldn't have been reason enough to revert the commits.
Introducing something like a `MEM_new<T>` and `MEM_delete<T>`
function might help with the the most common case of casting the return
type of `MEM_malloc`.

Going forward, I recommend first committing the changes that don't
require converting files to c++. Then convert the shading node files
in smaller chunks. Especially don't mix fairly low risk changes like
moving some simple nodes, with higher risk changes.
