Loot table API v2, iteration 2 (#1241)
* Improve loot table API

Alternative to #629.

- Deprecates all classes and methods that use outdated Yarn names.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.

Still WIP: LootTableLoadingCallback uses the deprecated FabricLootSupplier.

Update fabric-loot-tables-v1/src/main/java/net/fabricmc/fabric/api/loot/v1/FabricLootTableBuilder.java

Fix compilation

Create loot table API v2

Move incorrect classes and revert unnecessary change

Add test for replacing loot tables

Document FabricLootPools

builder() -> create()

Add accessor for LootPool.bonusRolls

Add loot pool builder method for bonus rolls

Use Blocks.DIRT.getLootTableId() instead of raw string in v1 loot test mod

Make links in deprecation docs cleaner

Make FabricLootPoolBuilder.copyFrom(pool, true) also copy bonus rolls

...and mention it in the javadoc

Remove copyFrom from v2 builders

It seems like a maintainability mess if Mojang ever decides
to extend loot tables, and the chosen boolean flags are arbitrary.
It also doesn't really have use cases apart from the internal use
in the copyOf methods, and even then users can replicate its functionality
with the other API methods.

Rename 'supplier' to 'table' in LootManagerMixin

Add 'stable' lifecycle to loot-table-api-v2, deprecate v1

Add internal comment for implementors about updates

Cancel all remaining callbacks when a loot table is replaced

Remove unused shadowed logger from LootManagerMixin

Migrate subproject versioning to new system

Start the AW migration

Update test mod

* Use interface injection

* Fix some issues

* Remove outdated bonusRolls test from LootTest

It's a vanilla feature now.

* Create transitive access widener module

* Replace LootTableLoadingCallback with two events

* Use friendlier exception message

* Add resource source tracking

* Add loot table sources

* Add resource pack source for DefaultResourcePack$1 (anon resource)

* Add license header

* Make FabricResource an internal API in resource loader

* Remove my TAW module

* Add loot table-related TAWs

* Run CI

* Fix LootUtil.determineSource giving null values

* Clarify LootUtil comment

* Rename loot-table-api => loot-api + minor comment changes

* Add README

* Fix mixin file name

* Use ImmutableMap.Builder instead of HashMap.computeIfAbsent in loot event impl

* Prefix accessor methods with fabric_ to prevent conflicts with loot v1

* Document mixins

* Document mixins more extensively

* Improve NRMMixin comments

* Change weird wording in FabricResourceImpl

* Minor updates

- Support new built-in mod respack source
- Fix ResourceMixin comment
- Add more docs to LootTableEvents.MODIFY
- Add package-info

* Add license header

# 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.
