Make plastic sortable for recycling, and make a multitude of items recyclable (#31593)

* Most plastic items are now recyclable, under the label "miscellaneous". Amounts to be balanced, currently same as recipe.

* Mineral tiles can be recycled

* Gold teeth and collection plates can be recycled

* Recycling sorter will now empty out crates and closets before sorting, if possible

* New recycling material category for the sorter, plastic. Many items updated to be considered such.

* derp recycling sorter fixes

* derp what was the point in creating a category otherwise

* just in case

* dorf recycling

* Smithing recycling? It's been a while and I don't remember what I was up to.

* Fix #28612 (You cannot recycle coins into their base metal)

* Blacksmithing recycling nearly done now,
Just some weirdness with tower shields left, plasteel component doesn't transfer materials correctly.

* All sheets with materials defined should actually have a .materials now, so I can grab an alloy sheet and use it's materials to decide what's being transferred instead of trying to guess of it's material type/hoping it has a material type at all. Fixes tower shields not having plasma from plasteel.
There's still a TODO in how materials are transferred to blacksmithing products, and a bug that predates my changes, but I've no idea how to go about either and this whole PR feels unatomic enough as it already is. I just wanted to be able to recycle plastic bags man, not overhaul crafting.

* Sorter will now consider crates it can't open as non-recyclable, since the recycler simply can't deal with those and it wouldn't make sense to create another way to unlock locked crates anyway. No more clogged recycling because of a closed crate.

* Update boomerang materials
