Enhance bot ladder climbing reliability

[sunzenshen]

Description

Addresses various ladder climbing failure scenarios that could cause bots not to be able to successfully climb ladders

• Leverage ladder climbing swim controls to decouple climbing with look direction
• Movement helpers to help bots align with ladder and dismount

Toolchain

• Windows MSVC VS2022

Dependencies

• Allow swim up and swim down controls to move the player up and down the ladder #1802

Script for commanding bots around the map to climb ladders:

nb_debug path;
sv_neo_bot_cmdr_enable 1;
sv_neo_bot_cmdr_debug_pause_uncommanded 1;
neo_ctg_round_timelimit 99;

Related navmesh scenarios that demo some of the edge cases handled by this PR:

• Match edges of Rogue pinhole ladder neoAssets#116
• Fix ladder NavMesh in rise roof backrooms neoAssets#106

Also relies on PR #1802 to enhance the directional reliability of climbing ladders.

(We could wait for that PR to be merged first, and then we could rebase on top of that commit.)

Looks good, the bots seem a lot smoother at navigating ladders now
