[Particle System] Renderer Mesh artefacts when Position/Normal attributes are set to float16

Visual Effects - Legacy


How to reproduce:
1. Open the user's attached project and Scenes/SampleScene scene
2. Observe the OriginalMesh GameObject in the Scene view
3. In the Hierarchy window, select ParticleSystem and observe it in the Scene
4. In the Project window, right-click on ASSET (see notes) and select Process Mesh Layout/GPUFriendly
5. In the Inspector window, observe that Position, Normal and Tangent attributes are float16
6. In the Scene view, observe the OriginalMesh and ParticleSystem

Expected result: OriginalMesh and ParticleSystem look the same as before
Actual result: OriginalMesh is the same, but ParticleSystem has changed and now look like triangles
