tweak(client/cl_spectate): Make gamer tag tickless

Make cl_spectate tickless

This was kinda bothering me while profiling my server that doesn't use monitor, so I made this part of the code tickless

@TasoOneAsia b-but... conflict with your own pr

[Ekinoxx0]

I could re-do/change this PR if needed after his commit is merged first, just need to know if something is blocking the merge of #591 🤔

Right now merging any client side lua is very risky because errors wont be printed, so we will have really hard time finding out and fixing issues.
It will take a few more months until we can merge that.

Seems understandable, implementing some sort of trycatch functions could be a solution with error handling being reported through a sentry. I suppose it would need approval from the Cfx team

Anyway I will keep following both PR and modifying them if needed 👍

Thanks for the PR.
Due to conflicts I'm merging it manually.
