Building IDs which are not covered by copy-on-write process was not implemented, which was causing parameters block not present, and, hence causing crashes in areas which expected parameters to present. First part of this change is related on making it so Copy-on-Write is optional for ID nodes in the dependency graph. Second part is related on using a generic builder for all ID types which were not covered by Copy-on-Write before. The final part is related on making it so build_id() is properly handling ParticleSettings and Grease Pencil Data. Before they were not covered there at all, and they need special handling because they do have own build functions. Not sure it worth trying to split those parts, as they are related to each other and are not really possible to be tested standalone. Open for a second opinion though. Possible nut-tightening is to re-organize build_id() function so that every branch does return and have an assert at the end, so that missing ID type in the switch statement is easier to spot even when using compilers which do not report missing switch cases. As for question "why not use default" the answer is: to make it more explicit and clear what is a decision when adding new ID types. We do not want to quietly fall-back to a non-copy-on-write case for a newly added ID types. Differential Revision: https://developer.blender.org/D10075
