In the previous state, we were relying on forcing the linker to include all libraries in the final binary and the global initializer to self-register every piece of the system. This change help moving away from this model, and allow users to compose pieces more freely. The current change is only "fixing" the dialect registration and avoiding relying on "whole link" for the passes. The translation is still relying on the global registry, and some refactoring is needed to make this all more convenient. Differential Revision: https://reviews.llvm.org/D74461
