Change Details

All performance tests are made on a non-visual replay of "Combat Demo Huge Auto" from trainer tools. Store system components on inside `CComponentManager` in stead of on the heap. I tried to improve memory locality (reduce cache-misses). I can't compare the results (I have to learn the tool a bit bether ;)) For me the median Frame time improved from 56ms to 52ms +/- 2ms Such a change can also be made for other(non-system) components. I used the system components because they were simpler to port and I assume system components are accessed more ofter resulting in a bigger performance difference. There could be future optimisation: - make somthing coresponding to `CmpPtr` without having to query the interface. (QueryInterface is currently the function taking the most cpu-cycles) - Get rid of interfaces and template `HandleMessage` on the type of message.

On my [[ https://gitlab.com/phosit/0ad/-/commit/ee229c591a8ebbbf1c6b316acd1c03c093952d14 | gitlab-repo ]] i implemented the change for only one component, It's easyer to review. All performance tests are made on a non-visual replay of "Combat Demo Huge Auto" from trainer tools. Store system components directly inside `CComponentManager` instead of in the map.
