This patch tries to fix an issue with the windows debug builds where the PDB file for python scripted interfaces cannot be opened since its path length exceed the windows `MAX_PATH` limit: https://github.com/llvm/llvm-project/pull/101672#issuecomment-2289481324 This patch addresses the issue by building all the interfaces as a single library plugin that initiliazes each component as part of its `Initialize` method, instead of building each interface as its own library plugin. This keeps the build artifact path length smaller while respecting the naming convention and without making any exception in the build system. Fixes #104895.
