### API Changes
- Interface inject `FabricBakedModel`
This change was done to eliminate the constant need to cast `BakedModel` to `FabricBakedModel`, especially when rendering sub-models. The implementations for the methods of `FabricBakedModel` were moved from `BakedModelMixin` to `FabricBakedModel` as default implementations. Some javadoc was updated to reflect this change.
- Deprecate the mesh consumer (`Consumer<Mesh>` retrieved from `RenderContext`)
This change was done to ensure consistency across all current and future contexts in which a mesh may need to be output to a quad emitter. The preferred direct replacement is the new method `Mesh#outputTo(QuadEmitter)`. Some javadoc was updated to reflect this change.
- Deprecate the baked model consumer (`BakedModelConsumer` retrieved from `RenderContext`)
This change was done to ensure consistent rendering of sub-models and to eliminate assumptions about what features a model uses. The preferred direct replacement is to use the appropriate `emit` method in `FabricBakedModel`. Some javadoc was updated to reflect this change.
Even though the consumer is now deprecated, the default `FabricBakedModel` method implementations still use it and renderers must still implement the getter. This is because Indigo and Indium sometimes apply smooth lighting differently based on if the quad came from a vanilla model or not. The eventual solution to allow all baked model consumer usage to be removed is to allow renderers to override the default `BakedModelMixin` and handle default vanilla models directly.
- Fix `QuadView#toVanilla`'s javadoc reporting the wrong minimum array size
### Implementation Changes
- Restructure `RenderContext` implementations
This change was done to reduce code duplication, improve standardization, and improve readability. Most code of `AbstractQuadRenderer` was moved into a new class called `AbstractBlockRenderContext` (which `BlockRenderContext` and `TerrainRenderContext` now extend), with the main buffering method being moved to `AbstractRenderContext`.
- Remove red blue color swap
It is unclear why this code was necessary in the first place. Indigo stores vertex color in ARGB format, then converts it to ABGR format only if the native byte order is little endian, and then reads the vertex color in ABGR format when buffering vertex data. This would mean that on big endian systems, all red and blue color components would be swapped.
Now, color is read in ARGB format when buffering and no color format conversion or swapping is done.
- Encode face normal
This change was done to improve the performance of meshes. Meshes already encoded all other geometry data, but the face normal would still have to be recomputed every time a mesh quad was rendered. Now, it is stored in the quad data header, so it is simply decoded, which is significantly faster.
- Fix some bugs
- Outputting a mesh via the mesh consumer would result in the emitter retaining the data of the last quad in the mesh.
- In non-terrain block rendering, the baked model consumer would incorrectly use the random seed provided by the block state instead of the passed random seed argument.
- When converting to or from vanilla quad data, the color would not be converted. Indigo uses ARGB format to store color, while vanilla quads use ABGR or RGBA. See the comment near the bottom of `ColorHelper` for more information.
- Fix TerrainRenderContext using incorrect overlay value of `0` instead of `OverlayTexture.DEFAULT_UV`.
- Improve performance of some code
- `QuadViewImpl#computeGeometry()` was being called before transforms and the cull test were applied. These operations can change the geometry and invalidate computed geometry data or cancel the quad outright. Calling the method explicitly in those contexts was also not necessary in the first place.
- A single `Vector4f` instance is now reused to transform the vertex position instead of allocating a new `Vector4f` for each vertex.
- The random seed lazy computation now uses a separate boolean instead of checking if the seed is `-1`.

The bitwise comparison is doing the opposite of what we want. It's currently checking for the *absence* of the BAKE_NORMALIZED flag. And if the flag is absent, it is normalizing. This should do the opposite.
A common source of crashes on modded Minecraft servers comes from modders accidently calling client only code from the client, this PR is another large step towards elimitating that.
This PR has been months in the making and years in the planning, requiring major changes to Loom & Loader. In recent Minecraft versions Mojang has made it easier than ever to cleanly split the jar, going against the status-quo of merging the client and server into one jar.
From the start we have designed Fabric to have a very clear split between client and common (client & server) code. Fabric has always encoraged keeping client only code seprate from the server, this can be seen at a fundamental level with the entrypoints in Loader. Fabric API's have all been designed with this mind.
This PR provides a compile safety net around Fabric API using client only code on the server. Even though there are almost 400 changed files, minimal changes beyond moving the files were required to achieve this in Fabric API, thanks to the effort of all contributors in the past.
These changes should not affect modders or players in anyway, a single "universal" jar is still produced. Im happy to awnswer any questions.
