[VFX] Empty Visual Effect Component generates about 14 KB of Garbage every frame in the Editor
1. Open the attached project named "Case_1305929"
2. Open the SampleScene
3. Open the Profiler Window and switch it to the Editor mode
4. Check the reading for GC allocations in the Memory section
5. Right-click in the Hierarchy window and add a new Visual Effect object
6. Observe the GC allocations again
Expected results: GC Alloc does not increase, or increases only marginally since a new VFX object is completely empty and does not have a VFX asset assigned
Actual results: GC Alloc increases by ~14KB OR by ~25KB if the Visual Effect object is currently selected in the Inspector window
Reproducible with: 7.5.2(2019.4.19f1), 2020.2.3f1(10.2.2), 2021.1.0b3(11.0.0), 2021.2.0a2(12.0.0)
Notes:
1. Reproducible with URP and HDRP
2. Does not reproduce in a Build
3. The memory amount does not seem to increase when the number of Visual Effect objects is increased. GC Allocated memory stays the same as described in the Actual results section
