NeoForge support (#166)

* Initial plumbing for NeoForge support

* Fix checkstyle

* Add ModPlatform.id

* Use NeoForge-specific cache

* Use NeoForge-specific dependency configuration

This is only for the "(neo)forge" configuration exposed
as API. The other configurations remain the same.

* Add test for basic NeoForge 1.20.2 projects

* Implement hacky fast track for NeoForge field migration

In other works, we skip field migrating for now.

* Disable patched decompilation task on Neo

* Disable mixin AP for building on NeoForge

* Many changes related to NeoForge mappings and remapping

* Code style and related fixes

* McpExecutor: Add support for downloading deps via Gradle

Also adds support for downloading a file without a repo
for NeoForm functions.

* Fix wrong configurations being used on NeoForge

* Fix mixin version detection on NeoForge

* Rename MinecraftPatchedProvider jar paths on NeoForge

* Test NeoForge against a client-only MC jar

* Add DFU for codecs, support NeoForge run config templates

* Centralise userdev config reading, support missing SAS

* Set up Shadow for bundling DFU

* Use correct name for NeoForm in cache files

* RemapJarTask: Fix check using isForgeLike for Forge

* MojangMappingsMerger: Complete and reorder mappings

* Fix SRG being used on NeoForge

* Fix SRG being used on NeoForge for ATs

* Use client pipeline for merged to avoid patch issues on Neo

* Update to architectury-loom-runtime 2.0

* Fix Minecraft jar name on Neo

* Fix MojangMappingsMerger having incomplete names

* Fix NeoForge mod dependency remapping using wrong mappings

* Quiet down MojangMappingsMerger

* Fix (Neo)Forge builtin coremods not being remapped

Fixes #146.

* Disable deprecated data generation API on NeoForge

* Use release version of the forge runtime

* Revert "Set up Shadow for bundling DFU"

This reverts commit 2bb8166744.

* Make NeoForge Field Migration work

* NeoForge shouldn't try to get datagen mods

* Fix checkstyle

* Remove mojang maven

* Split Forge and NeoForge extensions

* SimpleNeoForgeTest: Bump Neo version and fix Yarn version

* Remove resolved TODOs

* Re-enable joined NeoForm pipeline

* MPP: Rename srg -> intermediate jars

* Reintroduce namespace filtering for mapping trees

Should be a simple optimisation to avoid reading an
additional ns.

* ForgeRunTemplateTest: Fix code format

* Adapt SrgMerger into ForgeMappingsMerger (#169)

* Fix crash with NeoForge ext creation

* Adapt SrgMerger into ForgeMappingsMerger

* Update tiny-remapper

* Fix spotless

* Resolve reviews

* Fix checkstyle

* Remap ASMAPI.redirectFieldToMethod (#171)

* Remap ASMAPI.redirectFieldToMethod

* Move lastClassName outside the if

* Fix missing template variables in tests using forge/simple

* Add Java version to forge/simple test variables

* Fix changing patch version not affecting mapped game jars

Fixes #167.
