@compnerd @vgvassilev this is a redo of #145575, which I had to revert because it introduced a cyclic dependency |

## Purpose This PR is a re-application of llvm#145575 with independent definition of `ABI_BREAKING_EXPORT_ABI` that does not depend on `llvm/Support/Compiler.h`. It is one in a series of code-mods that annotate LLVM’s public interface for export. This patch annotates the ABI Breaking Checks interface in llvm/config. The annotations currently have no meaningful impact on the LLVM build; however, they are a prerequisite to support an LLVM Windows DLL (shared library) build. ## Background The effort to build LLVM as a Windows DLL is tracked in llvm#109483. Additional context is provided in [this discourse](https://discourse.llvm.org/t/psa-annotating-llvm-public-interface/85307), and documentation for `LLVM_ABI` and related annotations is found in the LLVM repo [here](https://github.com/llvm/llvm-project/blob/main/llvm/docs/InterfaceExportAnnotations.rst). ## Validation Local builds and tests to validate cross-platform compatibility. This included llvm, clang, and lldb on the following configurations: - Windows with MSVC - Windows with Clang - Linux with GCC - Linux with Clang - Darwin with Clang
