Crash on "mecanim::animation::SeekClip" and the Animators methods execution gets slower and slower when repeatedly calling the "RigBuilder.Build()" in the Player
How to reproduce:
1. Open the “AnimRiggingOverrideControllerCrash“ project
2. Open the “Assets>BugReport>BugReport_AnimationRigging“ scene
3. Navigate to “File/Build Settings“
4. Toggle on Development Build and Autoconnect Profiler
5. Build and Run
6. Let the Player run and observe the Profiler for a few minutes
Expected result: The spikes in the CPU Usage module stay about the same size and after a few minutes the Player does not crash
Actual result: The spikes in the CPU Usage module grow bigger and after a few minutes the Player crashes
Reproducible with: 1.2.0, 1.2.1 (2021.3.41f1, 2022.3.39f1), 1.3.0 (2022.3.39f1, 6000.0.12f1)
Reproducible on: macOS 14.5 (Intel), Windows 10 Pro (22H2)
Not reproducible on: No other environments tested

Resolution Note (fix version 1.3.x):
Fixed a memory inefficiency in the Animator BindStreamProperty and BindCustomStreamProperty functions. These functions are used when building a Rig via the Rig Builder and would allow duplicate stream properties to be bound multiple times. Therefore calling RigBuilder.Build many times would results in a slow down then eventual crash as identical bindings would continue to be loaded into memory.
