perf: Better realistic collision perf + CI benches (#3842)

This PR basically takes as much allocation out of the realistic collision hot loop as possible. This is done by inlining the vector/matrix/line clipping etc so far less readible. 

CI runners will be underwhelming in general, but relative movement is still good.
