Configurable bot cloak detection bonuses

[sunzenshen]

Description

• Allows server operators to customize bot cloak detection rates.
• Debug ConVar for watching bots as if they were cloaked all the time.
• Also separates out the factor of cloak being turned on versus cloak being disrupted.
• Bot observers are probably more forgiving about cloak disruption when target is firing unsuppressed weapons.

Toolchain

• Windows MSVC VS2022

I added ConVars for detection bonus values and bot difficulty detection thresholds so that anyone else can watch a bot match and tweak detection factors live. That said, how detection events feel seems like a subjective opinion, but I hope that these numbers can start as a reasonable baseline.

My intention with the initially submitted values are based on these intended profiles for the difficulty settings:

• Expert: Bots have slower reflexes but eventually zero in on you.
• Hard: Will sometimes miss you in a lapse of attention but otherwise will eventually find you if you linger.
• Normal: Bots are generally aware of standard ranges and movement, but if you don't aggro them, they sometimes will completely miss you or pass you by.
• Easy: This about the point that bots are absentminded and really struggle to notice you if you aren't performing loud activities like shooting.

Helpful Testing Commands/Scripting:

Start TDM Mode on Engage

neo_vote_game_mode 0; mp_restartgame 1; 

Enable bots considering everyone as always cloaked, and some example tweaking commands:

sv_neo_bot_cloak_debug_perceive_always_on 1;

sv_neo_bot_cloak_detection_threshold_ratio_easy   0.65;
sv_neo_bot_cloak_detection_threshold_ratio_normal 0.70;
sv_neo_bot_cloak_detection_threshold_ratio_hard   0.75
sv_neo_bot_cloak_detection_threshold_ratio_expert 0.80;

sv_neo_bot_cloak_detection_bonus_scope_range 1;
sv_neo_bot_cloak_detection_bonus_shotgun_range 5;
sv_neo_bot_cloak_detection_bonus_melee_range 50;
sv_neo_bot_cloak_detection_bonus_disruption_effect 30;
sv_neo_bot_cloak_detection_bonus_assault_motion_vision 60;
sv_neo_bot_cloak_detection_bonus_non_support 1;

Left some notes but this LGTM

@sunzenshen Btw, since we now treat warnings as errors in master, you might wanna rebase this on top of master to make sure it passes before merge. (I don't think it resets the reviews if you use the "Update branch" -> "Update with rebase" button in GitHub.)
