* NetGroupHandles are now unique and cannot reference a future unrelated group once the group it referenced has been destroyed.

- FReplicationWriter::UpdateDirtyGlobalLifetimeConditionals now marks subobject owner dirty - now fixed to not cause bad state transitons
- Added test for previouse bad case.
- Changed checks to ensures to avoid taking down server

This helps make sure reliable client RPCs sent right before the server gracefully disconnects a client by destroying their PlayerController are received, especially under packet loss.
Can be disabled by setting the cvar net.GracefulCloseEnabled.

* CreateGroup public API now requires an FName
* Passing NAME_None will let Iris autogenerate an unique name to the group (not recommended)
* Ensure and don't create a group if a valid name was passed but it's not unique
* Improve LogIrisFiltering verbose logs to output group names

The prioritizer consists of an inner sphere, outer sphere, a cone and a line of sight. Radii, field of view for cone, line of sight width and priorities are all configurable. Priorities cover the shape they're configured for except for the cone where the priority is linearly interpolated from the inner cone length to the full cone length. A 2D greyscale image is produced to memory by the VisualizeFieldOfViewNetObjectPrioritizer test.

* Added safer ways to access internal buffers held by a FNetBitArray and FNetBitArrayView
* GetWord() can be used to safely access the full 32bit value to modify 32bit entries at once.
* GetDataChecked(NumWordSize) can be used to access the raw array buffer but will also validate that the maximum word iteration count is within the bounds of the NetBitArray
* Reset() has been deprecated in favor of ClearAllBits()
Iris
* Replaced usage of deprecated NetBitArray::Reset
* Replaced a few usages of unsafe GetData() with safer GetWord and GetDataChecked
* Replaced Reset with ClearAllBits
[CL 33692839 by louisphilippe seguin in ue5-main branch]
* Support runtime NetBitArray reallocations when maximum replicated object count is hit.
* FReplicationSystemParams can now configure an initial size for netobjet lists that can grow up to the MaxReplicatedObjectCount when the initialize size is all assigned to registered netobjets.
* Use InitialNetObjectListCount to set the initial list size.
* Use NetObjectListGrowCount to set by how many indexes we grow and realloca all netobject lists.
* Hitting the maximum active replicated object limit will now cause a fatal error and kill the process.
NetDriver
* Split Iris config into two structs: ReplicationSystemConfigClient and ReplicationSystemConfigServer

* NetObjectFilter now owns the FilteredObjects list
* NetObjectFilter's now need to set the NeedsUpdate trait if they want to receive UpdateObjects callback telling them of dirty objects
* NetObjectFilter::UpdateObjects is no longer pure virtual
* NetObjectFilter's OnInit params is now const
* Added some safety tests by using ArrayView's instead of raw buffers

- Implemented support for capturing and caching CreationInfo which allows us to capture final snapshot of replicated objects data including information we need to send creation info to clients. This allows flushing of replicated state and rpcs even if the owning actor is destroyed.
- Iris now supports flushing state for Networked objects created and destroyed during the same frame.
- Autoflush behavior can be disabled by cvar net.Iris.EnableFlushReliableRPCOnDestroy 0

Iris - Object scope hysteresis support. Keep dynamically filtered out objects around for a specified amount of frames. Configure behavior via hysteresis profiles that determine the frame timeout per class. The filter config for a specific class can then mention the hysteresis profile in order to get the appropriate behavior. Config example is present in ReplicationFilteringConfig.h
Note: Hysteresis is enabled by default with a frame count of 6.
