This attempts to fix a lot of problems such as:

1. Previously ignoreSetSlot was basically always active client-side when ticking hotswap was enabled & the offhand was active. Since we only need to block that packet in very specific cases the check has been moved serverside and made a lot more selective. This also saves us from sending 2 packets to tell the client to ignore it + the one we're ignoring every tick. This fixes Inventory bugs #20, fixes Visual glitch when clearing inventory (1.5.3-pre) #16, fixes Display issue when using totem of undying and tinted arrows from EFR #11 (Not 100% sure but I can't reproduce anymore)

2. Any block that had the method onBlockActivated() used to be blocked from being harvested, having that method doesn't necessarily mean that the player will interact with it though. To fix that I stole the fake player & fake world from BlockRenderer6343 and use that to simulate onBlockActivated() clientside. I have tested it with a number of blocks that can activate and it seems to work as expected but it's very possible that there are some cases where it won't. (This affected a ton of blocks from https://www.curseforge.com/minecraft/mc-mods/artifice & likely a lot of other mods)

3. Ticking hotswap has been changed to use the actual offhand ItemStack rather than a copy. This fixes Some items do not update quantity after use (visual only) 1.5.3-pre #15

4. The arrow hotswap has been changed to check the BlockDispenser.dispenseBehaviorRegistry rather than check specifically for vanilla/EFR arrows. This should in theory allow us to support a lot more arrows/projectiles from other mods but has the funny side effect of hotswapping if you are using a bow in mainhand + armor (and a few other things) in the offhand, this doesn't affect gameplay and the bow will act as normal.

On top of that a few unused mixins have been removed & some static variables that the server used to track player specific states have been moved into OffhandExtendedProperty.
