Reproduction steps:
1. Open the attached project "ReproProj"
2. Open the “/Assets/Scenes/SampleScene.unity” Scene
3. Open Profiler (Window > Analysis > Profiler)
4. Enter the Play Mode
5. Click repeatedly the Button with text “Bake SDF“
6. Observe the Mesh usage under Memory Module in Profiler

Expected result: Baked Mesh is destroyed thus the usage does not change
Actual result: Mesh usage increases with each click

Reproducible with: 6000.0.63f1, 6000.2.14f1, 6000.3.0f1, 6000.4.0a5, 6000.5.0a2

Reproducible on:
Play Mode
Windows Standalone Player

Testing environment: Windows 10 Enterprise 21H2
Not reproducible on: No other environment tested

Notes:
- If you use the "Bake SDF (destroy via reflection)" button, the Mesh Memory usage does not increase
- Said button uses reflection to access MeshToSDFBaker.m_Mesh field and destroy it
