[1.21.1] Visualizer Rework

[Notenoughmail]

• Ability to register visualizer 'groups' per implementation of chunk generator extension
• in-world visualization done on server side
  • no need to recreate chunk generator
• rework permissions stuff to be compatible with new/arbitrary visualizer types
• make "preview world" button in more tab be per dimension with cge
• Make Rocks visualizer use RocklayerSettings#sampleAtLayer instead of ChunkDataGenerator#generateRock [Done in 1.5.1/1.20.1]

Concept:

interface IVisualizer<G extends ChunkGeneratorExtension, C> {

    void draw(int imageX, int imageZ, MutableImage image, int xPos, int zPos, G generator, RegistryAccess registryAccess, Int2ObjectOpenHashMap<Component> colorDescriptors, C cache);

    Component colorKey(RegistryAccess registryAccess, C cache);

    Component name();

    C createCache(RegistryAccess registryAccess, G generator);

    void afterComplete(MutableImage image, G generator, RegistryAccess registryAccess, C cache, Int2ObjectOpenHashMap<Component> colorDescriptors);

}

enum NoopCache { INSTANCE; }

interface IUncachedVisualizer<G extends ChunkGeneratorExtension> extends IVisualizer<G, NoopCache> {

    default NoopCache createCache(...) { ... }

    default void draw(..., NoopCache cache) {
         draw(...);
    }

    void draw(int imageX, int imageZ, MutableImage, int xPos, int zPos, G generator, RegistryAccess registryAccess, Int2ObjectOpenHashMap<Component> colorDescriptors);

}

interface IGeneratorVisualizer<G entends ChunkGeneratorExtension, S extends IVisualizerScale, SG extends IVisualizerScaleGroup<S>, V extends IVisualizer<G, ?>> {

    List<V> allVisualizers();

    SG scaleGroup();

    List<V> allowedVisualizers(ServerPlayer player, Server server);

    Component name();

    boolean supportsRockEditing();

    void additionalSyncronization(SynchronizationRequest syncRequest);

    G recreate(G generator);

    StreamCodec<G> generatorCodec();

    StreamCodec<List<V>> visualizerCodec();

}

class SyncronizationRequest {

    <T> void request(RegistryKey<? extends Registry<T>> registry, StreamCodec<T> elementCodec)

    <T> void request(RegistryKey<? extends Registry<T>> registry, StreamCodec<T> elementCodec, TagKey<T> tag);

    <T> void request(RegistryKey<? extends Registry<T>> registry, StreamCodec<T> elementCodec, Predicate<Holder<T>> filter);

    <T> void syncTagContents(TagKey<T>... tags);

}

interface IVisualizerScaleGroup<S> {

    int blocksPerPixel();

    Component formatScale(S scale);

    List<S> scales();

    Codec<S> codec();

}

interface IVisualizerScale {

    int sizeInPixels();

}
