Bunch of fixes for TF2's VScript update (2022-12).

• Used CTFPlayer::m_hDisguiseTarget in place of ::m_iDisguiseTargetIndex; the latter no longer exists.
• Used CUtlVector<T>::Count() in place of the deprecated CUtlVector<T>::Size() method.
• Changed the client menu logic to use the new IVDebugOverlay::AddScreenTextOverlay method. This renders the text in screen space, preventing the text from shifting around with the player's aim.
• Other build changes for compilation to succeed:
  • Workflow now uses Ubuntu 20.04, which is the oldest supported Linux runner currently available.
  • NO_HOOK_MALLOC / NO_MALLOC_OVERRIDE definitions added to the compile stage of games that require it.

That's all the energy I have to work with for RCBot for now. See you in 8 months.

• Implements some fixes for the VScript update.
  • This includes the debug overlay fix.

• Automated build process now attaches archives containing debugging symbols to the releases, in case any users would like to investigate crashes on their own.
  • These are the dbgsym.*.tar.gz archives. Again, they are optional downloads.
• Courtesy of @caxanga334, RCBot2 can now be compiled against SDK2013 / BMS. However, none of the bot logic from their fork is currently integrated into the project, nor are binaries actually provided for either of those branches of the engine.

• Fix to restore the ability to build RCBot2 both with or without SourceMod bindings (#19). Functionality should be otherwise unchanged, but the build has changed some.

• The logging framework now has color support through the ANSI escape sequences, Windows console attribute, and Source game client console print formatting systems.

• Reverts the changes implemented in r22 / 47c20ff (attempted fix for third-party plugins overriding RCBot-desired classes).
  • A bug was discovered where bots would tend to spawn as a particular class; this is considered a regression.

• Removed functions that generated example files accessclients.ini and mods.ini, preferring to raise an error instead.
  • The rationale for this change was that (1) configuration files are part of the installation, deleting them is user error and (2) keeping the configuration files in sync with code is a hassle.

• Refactor to replace FILE* pointers with std::fstreams for modernization.
  • ⚠️ Testing for regressions is very important here. It passes my personal smell test on my test instance for bots loading in and running properly on a known map, and I've performed round-trip testing for waypoints (loading and saving them and ensuring they match). That said, be sure to have backups of other waypoint-related files just in case.
