Implemented smithing table functionality

[HimmelKreis4865]

Introduction

This PR adds working smithing tables to pocketmine.
There are no known issues or problems

Changes

API changes

Amor->setTrim(ArmorTrim)
Armor->getTrim() : ?ArmorTrim
Armor->clearTrim()

SmithingTableInventory->getInput() : Item
SmithingTableInventory->getAddition() : Item
SmithingTableInventory->getTemplate() : Item

The new enums: ArmorTrimPattern & ArmorTrimMaterial (required to construct ArmorTrim)

Tests

Tested ingame with the smithing table several times:

Tested the code

$player->getInventory()->addItem(VanillaItems::LEATHER_CAP()->setTrim(new ArmorTrim(ArmorTrimMaterial::QUARTZ, ArmorTrimPattern::EYE)));

There's not much more I can do at this point, everthing is fixed except for save ids.

[jasonw4331]

Looks pretty good to me, one comment.

[pandaaaBE]

Looks finished now :)

[HimmelKreis4865]

yeah, ready to be reviewed again.

Looks mostly OK.

I'm a bit uneasy about allowing custom armor trim patterns because they'll generate confusing errors if the objects are duplicated. The ArmorTrimPattern and ArmorTrimMaterial classes should use the NotCloneable and NotSerializable traits.

For posterity: I think this got stalled because I wasn't happy about using RegistryTrait for armor patterns and trims.
My issue with that is mostly around wanting to use enums wherever possible, but we run into #6292. I don't feel good about introducing inconsistent APIs around this stuff, but no resolution was reached in internal discussions about this.

Will revisit this soon ™️
