PersistentDynamicRegistryHandler

This solves a bug in vanilla where datapack added biome IDs are not saved to disk. Thus adding or changing a biome from a datapack/mod causes the ids to shift. This remaps the IDs in the DynamicRegistryManager in a similar manner to the normal registry sync.

See: https://bugs.mojang.com/browse/MC-202036

This may cause issues when vanilla adds biomes in the future, this should be fixable by also remapping the static ID map vanilla keeps.
