Optimize event-function context creation

[D8H]

I observed 2 cases when the optimization is noticeable. It also probably reduces memory fragmentation which may improve performance in heavy games.

Free functions without object parameters

4,000,000 calls to a free function with a JS event only accessing parameters is 3 times faster:

Life-cycle functions

10,000 objects with a behavior where the doStepPreEvents contains a JS event that only accesses the object and behavior is a bit faster.
