Improve `mc_toolhandler` system

[Lowie375]

• Reverse mc_toolhandler registration flow
  • Register tools from API function calls in other mods instead of from tool scrape in mc_toolhandler
  • Make mc_toolhandler a dependency instead of a dependent when registering tools
• Make mc_toolhandler put managed tools into toolbox by default (if mc_toolmenu is present)
• Add inv_override property to allow tools to be placed in different player inventory lists by default
• Replace various MineTest-defined helper functions in mc_toolhandler with mc_helpers equivalents
• Abstract out core of get_player_item_location function into mc_helpers.getInventoryItemLocation
• Make list_info local

Refactor is mostly complete! Will re-open the PR once support for tool groups has been re-implemented

Have noticed a couple of issues that need to be fixed with mc_toolhandler; marking as draft until those have been fixed

I am not sure which commit deleted it, but we should probably automatically check and ensure that all players join the game with the student notebook and the tutorial notebook and all teachers join with the student notebook, the teacher remote, and the tutorial notebook.

Noted! Will add a property that allows the default inventory for an item to be overridden. That should allow tools like the student notebook and teacher tools to always go to the "main" inventory

Also, I noticed that the tutorial recording tool is still automatically given from an on_joinplayer callback somewhere and is not registered in the toolhandler system yet. Is that forthcoming in the draft tutorial framework PR?

Yep, that has been changed on the features/tutorial_recording branch. However, that branch is using an older version of mc_toolhandler, so I'll just register the tools on this branch and merge develop into features/tutorial_recording after this PR is pushed
