Loot table API v2

Browse source 
- Deprecates all classes and methods that use outdated Yarn names.
- Adds FabricLootTable and FabricLootTableBuilder to replace
  the LootSupplier naming variants.
- Deprecates LootEntryTypeRegistry and LootJsonParser
  as their functionality is exposed in vanilla now.
- Adds methods to FabricLootPoolBuilder for working
  with collections as builder parameters.
- FabricLootPool and FabricLootTable/Supplier now return immutable lists
  instead of modifiable fixed-size ones.

# Fabric Loot API (v2)
This module includes APIs for modifying and creating loot tables.
## [Loot table events](src/main/java/net/fabricmc/fabric/api/loot/v2/LootTableEvents.java)
This class provides two events for modifying loot tables.
`LootTableEvents.REPLACE` runs first and lets you replace loot tables completely.
`LootTableEvents.MODIFY` runs after and lets you modify loot tables, including the ones created in `REPLACE`,
by adding new loot pools or loot functions to them.
### Loot table sources
Both events have access to a [loot table source](src/main/java/net/fabricmc/fabric/api/loot/v2/LootTableSource.java)
that you can use to check where a loot table is loaded from.
For example, you can use this to check if a loot table is from a user data pack and
not modify the user-provided data in your event.
## Enhanced loot table and loot pool builders
`LootTable.Builder` and `LootPool.Builder` implement
injected interfaces ([`FabricLootTableBuilder`](src/main/java/net/fabricmc/fabric/api/loot/v2/FabricLootTableBuilder.java)
and [`FabricLootPoolBuilder`](src/main/java/net/fabricmc/fabric/api/loot/v2/FabricLootPoolBuilder.java))
which have additional methods for dealing with already-built objects and collections of objects.
Those interfaces also have `copyOf` methods for creating copies of existing loot tables/pools as builders.
