Refactor item components to be stored as a map

Summary

Infrastructure "Refactor item components to be stored as a map"

Purpose of change

Assigning components to crafting results from a list is pretty sketchy, when it should get split up to multiple result items. I need it to be less sketchy for #60885.

Describe the solution

Turn components into a map and make a wrapper class around it for some easier handling. Then adjust all the code to work again. Also replace a hacky solution in the invlet test with a proper one.

This adds a fairly prevalent error message when components can't be evenly distributed to resulting items when crafting a recipe. I do believe that needs to be fixed one way or another, but if it's too much of an annoyance, the messages can be removed and some automated way to identify such problematic recipes can be devised.

Describe alternatives you've considered

Go even further with the refactor, but this wasn't planned for the charge removal project so I don't want to spend more time on it than necessary.

Testing

Not much yet. Game loads old saves, can disassemble old items, can craft new items, tests pass locally.
Also indirectly tested with #60885 and #63704.

Additional context

[misterprimus]

Does it avoid adding consumables like welding rods and bone glue to the components list after crafting to avoid recovering items that should be unrecoverable? #51172

[mqrause]

Not this one, but I added something to do that in #60885.

Actually no fixes for that included anywhere for now.
