Subject: [PATCH] DataComponent API

Exposes the data component logic used by vanilla ItemStack to API
consumers as a version-specific API.
The types and methods introduced by this patch do not follow the general
API deprecation contracts and will be adapted to each new minecraft
release without backwards compatibility measures.
