"Call function" anim node: - Adds the ability to call functions at different points in the anim graph execution (and under different conditions, e.g. when a branch has started blending in). Only thread-safe functions are allowed to be called. - Adds a thread-safe override point BlueprintThreadSafeUpdateAnimation, called on worker threads for the main instance and for linked instances when they are relevant in the graph (only one call per frame for linked layer instances). Subsystems: - Added new override points pre/post event graph(s) (moved override point for worker thread work to around the thread safe update function call). Improves property access integration: - Property access now shows (and allows the user to override) the call site of accesses. This is to allow users to see when their property access calls will be made, hopefully making its use less confusing for power users. - Tweaked UX for property access nodes and dropdowns. - Anim node pins now have property access bindings in-line on the pin. Also adds the abilility for the anim graph to opt-in (via a config flag) to more stringent thread safety checks. Disabled by default for now as this requires content fixup. #jira UE-115745 - Anim Blueprint Encapsulation #rb Jurre.deBaare [CL 16434092 by Thomas Sarkanen in ue5-main branch]
