Blenkernel: move DerivedMesh.c to c++

Required changes to make it compile with clang tidy:
* Use c++ includes like (e.g. climits instead limits.h).
* Insert type casts when casting from void* to something else.
* Replace NULL with nullptr.
* Insert casts from int to enum.
* Replace designed initializers (not supported in C++ yet).
* Use blender::Vector instead of BLI_array_staticdeclare (does not compile with C++).
* Replace typedef statements.

Ref T83357.
