Geometry collection asset - move cooking of render data out of the serialize method
- This is required to support async loading and avoid the resource initialization from calling GameThread checked methods
- Move cooking to both PreSave and PostLoad
THis simplifies the code as PostLoad and PreSave are not called during transactions

* packed and re-ordered data in structures to minimize padding as much as possible
* reduce simulation parameters data by 80 bytes ( 112 if stripping the deprecated members )
* remove dead code

- When attributes are missing we regenerate them ( editor time only , so assets will be fixed next cook )
- in the future we should revise the way we cook those assets
