SmArtKar 19333152cb Softens material requirements for printing custom material objects (#96258)
## About The Pull Request

Changes hard density and flexibility requirements to be flag checks for
valid item crafting flags for armor, and non-amorphous materials for
everything else (so basically anything but snow and raw sand (not
sandstone))

## Why It's Good For The Game

The restriction was mostly futureproofing and doesn't do much currently,
I don't see this adding much, this just ended up removing some content
like meat toolboxes/armor on accident. (this was intended to block
snow/paper/sand from being made into material items, but after thinking
a bit paper material stuff does make some sense)

## Changelog
🆑
balance: You can make toolboxes out of meat and paper again
