[v9] fix: prefer named functions, for loops in hot paths

[AlaricBaraou]

Following the discussion here https://discord.com/channels/740090768164651008/740093168770613279/1023859404111613962

I went to add a name function to remove this anonymous function from the performance tool report

I also thought that we could replace the forEach with for loops where applicable.
With the for loop there isn't a need to use a named function at all in the end.

So I went through the files and replaced the forEach loop that looked safe to replace.

I'm expecting a gain of 1µs per frame with that

The perf gain is probably neglectable but it removes some noise from the performance and also use less memory for one of them that was creating a new array on each call ( cancelPointer )

Looks good. Did the same for events so the flame graph is consistently traceable.

Is there a reason for targeting v9 or is this something you'd want in v8?

[AlaricBaraou]

I just saw a comment from Paul asking to target V9
If it can also be available on V8 I'm all for it.

I initially made the change for V8, just made the PR if you want to use it. #2541

I didn't run the lint / tests on V8 either but the exemple seemed to run normally.

No worries. I'm happy to backport this as a fix since it's affecting quality control.
