Inventories

[ReCore-sys]

Inventories are a part of minecraft. We are implementing minecraft. It's fairly simple.

Description

This PR adds support for inventories as well as placing (some) blocks correctly, based on what you are holding. While not super useful on it own, it is extremely useful for other stuff. This is a somewhat minimal implementation however, since item components hasn't been implemented, though we currently don't have anything like anvils or enchantments so this isn't an issue for now. Additionally the block placing is fairly rudimentary and can't handle stuff like blocks being placed facing certain ways or items not having the same name as the block they place.

This PR does also fix a bug relating to favicons added in #206

Motivation and Context

Having inventories is vital for both building general gameplay.

How has this been tested?

Unit tests and in game testing
