The purpose of `NodeTreeRef` was to speed up various queries on a read-only `bNodeTree`. Not that we have runtime data in nodes and sockets, we can also store the result of some queries there. This has some benefits: * No need for a read-only separate node tree data structure which increased complexity. * Makes it easier to reuse cached queries in more parts of Blender that can benefit from it. A downside is that we loose some type safety that we got by having different types for input and output sockets, as well as internal and non-internal links. This patch also refactors `DerivedNodeTree` so that it does not use `NodeTreeRef` anymore, but uses `bNodeTree` directly instead. To provide a convenient API (that is also close to what `NodeTreeRef` has), a new approach is implemented: `bNodeTree`, `bNode`, `bNodeSocket` and `bNodeLink` now have C++ methods declared in `DNA_node_types.h` which are implemented in `BKE_node_runtime.hh`. To make this work, `makesdna` now skips c++ sections when parsing dna header files. No user visible changes are expected. Differential Revision: https://developer.blender.org/D15491
