[PadSkinningStreamBuffers branch] Quickly changing certain properties in the SkinnedMesh sample causes GameLauncher to crash

[LB-ArturZieba]

Describe the bug If Segments Per-Mesh, Vertices Per-Segment, or Sub-mesh count properties are changed quickly in the SkinnedMesh sample, the AtomSampleViewer.GameLauncher crashes.

It should be noted that no error.log/.dmp files were generated and Game.log did not contain any additional information.

This issue also occurs on Android project that was deployed from Windows.

Due to time constraints it was not yet possible to confirm if the issue occurs on the Development branch of AtomSampleViewer.

This issue should be treated as Major priority.

Steps to reproduce

1. Launch AtomSampleViewer.GameLauncher.
2. Go to Samples > Features > SkinnedMesh.
3. Move sliders quickly on one of the properties: Segments Per-Mesh, Vertices Per-Segment, or Sub-mesh count.

Expected behavior AtomSampleViewer.GameLauncher remains stable.

Actual behavior AtomSampleViewer.GameLauncher crashes.
