b735c66d - Reland 'Update llvm::Registry to work for LLVM shared library builds on windows' (#109024) (#112640)

Reland 'Update llvm::Registry to work for LLVM shared library builds on windows' (#109024) (#112640) Fix missing extern templates for llvm::Registry use in other projects of llvm Windows doesn't implicitly import and merge exported symbols across shared libraries like Linux does so we need to explicitly export/import each instantiation of llvm::Registry. Updated LLVM_INSTANTIATE_REGISTRY to just be a full explicit template instantiation. This is part of the work to enable LLVM_BUILD_LLVM_DYLIB and LLVM plugins on window.
