Major refactor

[Galaco]

Summary

Major refactor in this PR. Tons of new usability & debugging features. Massive performance & quality improvements overall.

Changelog:

• feat: many new convars, for debugging and rendering tweaks
• feat: add support for autocomplete convars in console
• feat: Add performance monitor logs
• feat: Add debug renderer for features such as physics collision rendering
• feat: Add instanced rendering for staticprops
• feat: Add support for worldvertextransition shader (displacement painting)
• feat: Support for auto exec.cfg
• feat: Barebones A2S query UI; some semblance of structure for introducing client networking
• feat: Very rudimentary player controller
  • Notes: Pretty buggy right now; mostly okay on solid surfaces
• refactor: Add loading ui, including async world loads
• refactor: many services and separation of concerns
• fix: Prevent closing menu when no map loaded
• fix: fixed tilmestep on physics simulation
• fix: many model rendering and crash issues
• perf: optimized console logs performance
• perf: Cache static VAOs per material for faster rendering
• dep: Bump various dependencies
• dep: Remove usage of archived inkyblackness packages

There were a lot of convars added for debugging as go. A few highlights:

• developer
• noclip
• Many debug specific commands (r_drawplayercollision for example)

Known issues:

• This is primarily tested against maps for cs:s and Garrys Mod. Most maps don't crash at this point, but some do render incorrectly. (cs_office, cs_italy seem to have to texture related issues; probably the texStringData format is different than expected? although that is actually an issue with galaco/bsp)
• ze_last_man_standing does crash. Only map I've found so far that fully crashes. This seems to be connected to galaco/studiomodel handling having a parsing bug that causes an OOM.

About this project

The objective of this PR is to move the project along in 2 areas:

1. Correctly rendering maps that can be explored in a performant manner
2. Eventually supporting this as a thin alternative client to some source engine games. CS:S nosteam would be the primary target here initially. No real plan to implement the full game clientside; spectator mode & HLTV would be enough to call this a resounding success
