Mod Compatibility: Only load files within "mod_interactions" if requisite mod is loaded

Summary

Infrastructure "Mod Compatibility: Only load files within "mod_interactions" if requisite mod is loaded"

Purpose of change

Allow mods to dynamically load / unload content based on if other mods are loaded.
Fixes #71761

Describe the solution

When loading mod json files, first ignore any file within the mod_interactions folder. Then, read the directories within the mod_interactions directory. Compare these directories to the active mod ids, and if there is a match, load the files within that specific directory.

Style Scheme:

• "mod_interactions" folder
• sub-directories must be named after the mod_id for them to be loaded

Renames all existing mod interactions folders to meet this standard

Programmatic Explanation

load_mod_data_from_dir()

• wrapper method for add_mod_data_from_path().
• Used in the load_world_modfiles() and load_packs() methods

add_mod_data_from_path()

• Implements the new functionality of only loading folders in mod_interactions if the requisite mod is loaded
• Does so by calling the new get_files_from_path_with_exclusion() method to ignore mod_interactions, and then reading all directories within the mod interactions file and only loading them if the requisite mod is loaded.

get_directories()

• returns every directory within the given directory. Made because the existing directory methods with a blank pattern input return an empty vector.

get_files_from_path_with_path_exclusion()

• similar to get_files_from_path, but with an extra parameter that reads the full path of each file and rejects it if it matches.

name_contains()

• added parameter to allow reading from full path rather than just the filename.

Describe alternatives you've considered

Currently, this solution does not support multi-mod interaction folders. IE, a folder named "magiclysm,aftershock" or similar that is only loaded if both Magiclysm and Aftershock are loaded.

Testing

Did the following with custom edits to mods such as copy-from'ing mutations.

Tested that mods without mod_interactions folders don't crash / throw errors
Tested that content within mod_interactions directory is hidden by default unless correct mod is loaded.
Tested that mod_interaction folder content is after every mod is loaded. Mod_interaction folder content is still loaded in the same order as the mods they're from in comparison with eachother.

Additional context

Does Not Do:
Allow extra definitions of the same id within the mod_interactions file. IE: tool id named "tool_a" within the main mod folder with a redefinition of "tool_a" in "mod_interactions/aftershock" folder. The logic preventing this is separate but I may adjust it in another PR.

What happens if I put in a copy-from in one mod on a mutation only found in a second mod, but due to load order, the copy-from is loaded first (like, if I make an XE interaction in MoM where Ierde are immune to telepathy, but XE loads after MoM)? Is the copy-from ignored and the original trait wins?

The goal is for the copy from to load last regardless of load order. Right now this is still in the testing / dev stage so I'm not sure if that part works. Currently I've just confirmed that the files are / are not loaded
