Unifies all context destructors to have a form of PetscCtxDestroyFn == PetscErrorCode (*)(void **)

Changes the previous subset of destructor APIs that used PetscErrorCode (*)(void *) (mostly those that
used PetscContainer

- Now allows any context to be a PetscObject
- Will provide a cleaner mapping to bindings in other languages
- Simplifies the maintenance of PETSc source code; improves clarity

Not backward compatible, compiler warnings will tell users what functions need to be updated
