Expand the sections regarding Jitter, Stutter and Latency

[darksylinc]

This guide has basically two parts:

1. The result of thorough examination of all the problems found that were not caused by Godot (but were attributed to it). This adds an in-depth guide on how to locate and fix such issues.
2. A guide to the new code introduced by PR Improve pacing, latency, and add tweakable options godot#106221 which still needs to be merged.

This is my first PR to godot-docs so please point out if I made a mistake and I apologize any mistake that could've been solved with a RTFM (I did read it, but I probably missed something).

Looks great! I've made stylistic suggestions but the contents are pretty solid.

We should see if we can remake the Windows screenshots with fully English text later on, but it's not critical for getting this merged as the locations for the settings are obvious enough.

Thanks @Calinou for the editorial review. I've applied your fixes.

I've also added 2 more changes:

1. I added a note that nvidia-smi.exe exists on Windows too (but it is rarely a problem on Windows). Look for "nvidia-smi.exe" in the document.
2. Added "Third-party software" section.

Agreed. I tried to get them in full English but some text stayed in Spanish even after installing the English language pack and switching to it.

Suggested change

- RGB Led control software. A lot of software to control RGB lights (whether it's the keyboard, mouse, RAM sticks, fans, GPU, etc) are poorly written and known to cause stutter and jitter problems. Uninstall them. Prefer purchasing devices that are compatible with `Windows 11' Dynamic Lighting <https://support.microsoft.com/en-us/windows/control-dynamic-lighting-devices-in-windows-8e8f22e3-e820-476c-8f9d-9ffc7b6ffcd2>`__ control.

Should be good to merge after applying suggestions and rebasing.
