Removed direct access to currently compiling BP class to restrict unguarded mutation. Const-corrected various accessors and overrides. Moved UObject-based compiler subsystems to 'handlers' and removed UObject dependency. Moved from set of virtual functions on subsystems/handlers to a restricted set of contexts passed to specific multicast delegates that handlers subscribe to. Removed anim class subsystems. Moved property access code to engine module (editor code is still in a plugin). Fixed nativized builds where anim BPs have nativized/non-nativized classes in the hierarchy #rb Dan.OConnor #jira none [CL 14278258 by Thomas Sarkanen in ue5-main branch]
