Add flag for strip render data on cook to Geometry Collection.
This can be used if we have a non-native rendering replacement such as using ISM pools.
Added p.GeometryCollectionAssetForceStripRenderDataOnCook as a per-project way to force this.

This is built as part of geometry collection DDC contents.
Reworked scene proxy to use this data. Some big changes there:
* Tidied up hit proxy code so that all hit proxy clients use the same path.
* Removing of internal faces are now handled without an additional index buffer by always storing internal faces at the end of a section and providing different section descriptions for including internal faces.
* Dynamic geometry hiding in editor is now done by zeroing transforms instead of rebuilding the index buffer.
